Please explain, as this:
indicates she is planning quite well and purposefully.
I don’t eat salad. I’ll eat the ingredients in a salad, but I don’t eat salad of any sort. For example, when work gets a catered lunch usually there’s a green salad. I’ll pull out a couple of slices of tomato and cucumber and maybe a crouton, but I won’t get a big scoop of salad. (I don’t take very much because it’s not cool to leave a bowl of nothing but lettuce.) If you dumped the salad in a pita with some meat I’d eat it. Anything but green salad I won’t really touch at all (I might pick some fruit out of a fruit salad but they usually have cantaloupe which I find nasty.)
A not by choice thing: I have to be careful not to eat too much bland or soft stuff. I’ll end up not being able to get it down (literally, without getting too TMI). Eggs (by themselves) are a big one I have to watch for (which is a shame, because I love devilled eggs), but bread, sandwiches, cereal, and casseroles have all tripped me up before. If I have a contrasting drink and side I can usually manage. It hasn’t really acted up much since college, but I had a relatively bad incident a month ago when I was eating bologna sandwiches for basically every lunch and dinner.
I don’t like potatoes and I don’t drink soda or other really sugary drinks. I’ll admit I’m somewhat of a picky eater but I disguise it well.
I can’t eat with a hat or headband on. I can feel my skull moving and it’s weird.
I often either don’t get hungry, or will be hungry but completely uninterested in eating.
I don’t think she’d notice. It’s a drunk thing. Cold skim milk mixed with the flakes. Eats them then falls asleep.
For me salad comes after the main course. Before the fromage (or sometimes with the fromage).
Say what?! (no idea what food “fromage” is so I looked it up…)
Anyway, I tend to eat the stuff that tastes better last, even separating a mixed food; for example, chicken stir-fry, which I eat vegetables and rice first and chicken last (with some rice left because it tastes better that way). Not usually that obvious though, except when I eat something like ice cream with peanut butter/cookie dough pieces, then I suck the ice cream off and spit out the pieces to eat last. Other stuff (already separate), I eat a bit of each in turn so that whatever I like the most I eat last. Also, not so much now, but when I was a kid I didn’t like mixed foods either (that weren’t already mixed).
This!
I tend to order food in restaurants based on the side dishes or veggies, rarely based on the protein.
I eat pizza with a fork by eating the toppings, eating the cheese, scraping the sauce and doughy part of the crust with my fork and eating it together and then chucking what’s left. I only do this at home!
I have to have water or unsweetened iced tea to drink when I eat. I can’t eat without a drink and really don’t like sweet drinks.
I had a friend who ate one thing at a time, clockwise. He didn’t have a problem with all mixed together things like curry over rice, but even spaghetti and meatballs he would eat the meatballs clockwise.
Me, I don’t like my glass to be filled more than, say, 2/3 of the way. For some reason I am very uncomfortable with a full glass. I’ve even poured water out of an overfilled water glass. Doesn’t bug me at restaurants though. Only in a home kitchen.
I do not eat wet or soggy bread. Ever. I will not put tomatoes on sandwiches because it makes the bread too wet. I get very upset at places that put too much mayo or mustard or any kind of sauce on (hello, Panera) because then it leaks out the edges and makes the bread too wet and then I have to rip that whole part off. If a dinner roll has touched the juice of something else on my plate, that part must be ripped off. I have a particularly hard time with takeout subs because often the sauce or vinegar or oil or whatever will leak out in transit, get all over the top of the sandwich, and then I have to toss the whole thing. The texture of soggy bread makes me gag and even touching it is cringeworthy.
This is why when I make pizza at home, I use egg matzo for the crust.
I have the “don’t want foods touching” thing. I also can’t stand some textures, such as soggy pastry.
My husband eats pizza with a fork, I favor the finger-food approach. I do eat pizza in layers, and sometimes do that to lasagna.
I do this too, for pizza and lasagna (of course, lasagna tends to come apart anyway); I first eat the crust at the edge, then the topping, then separate the sauce/dough from the bottom crust, eat the bottom crust, then eat the sauce/dough parts like a sandwich (sauce sides together, I almost always have two pieces, but one piece can be folded in half). Of course, some kinds of pizza don’t separate easily so I don’t separate it but still eat the edge crust first (even when I am not at home, not that anybody has made mention of it).
I never knew anyone else that ate pizza in layers!
For me it’s sauces if any kind must be spread evenly over the whole item.
No pool of gravy in mashed potatoes, butter must be smeared evenly from crust to crust, I especially despise getting a mouthful of any one condiment and most especially any sort of mayo or miracle whip. Eeew.
Even onions and mushrooms on a steak must be have enough to eat with every bite or else I am very unhappy.
I absolutely HATE mint flavor in food, hate it hate it!
The only time I have ever been ok with it is when it is very subtle, like in that middle eastern cucumber soup whose name is escaping me.
I like to finish my (touching) food evenly. I like the irregular parts because they must be special. I have to have something to drink, always. It generally takes me 20-30 minutes to eat. I always eat the best stuff first in case I keel over dead before I’m done. (Wouldn’t want to have missed out.)
I HATE to throw food out. I think it comes from a time in my childhood when we were really broke and we were always hungry. The good news is that it got me over any picky eating habits I had; I’d eat just about anything we were so hungry. The bad news is that even now when I see my wife throw out food, even leftovers we’re already reheated once I’m like “Why did you throw that out?! I would have eaten that!”
Most recipes I encounter are very difficult to scale down to 2 people, so in my household, leftovers are pretty much inevitable. Neither of us objects to them (in fact, there are some foods we prefer to do in big batches for later reheating). I agree with your wife’s style. That way, she (I assume she’s the primary cook, based on your phrasing) spends less time both in the cooking stage and the cleanup stage. Much more efficient that way. 
I will not eat an un-centered sandwich. When I make my own, I of course lay the contents evenly to ensure that every bite is equal to the next. When ordering, I will actually take the sandwich apart and center all of the contents. I will not abide a sandwich with big bites of bread, but no meat, then in a different part huge chunks of tomato, or other uneven foolishness. Must be balanced.
I can’t stand crumbs in the margarine, or butter in the jam jar. Always clean the knife first.
I maintain the proportions in the food I take. If there’s meat and veges, I try and take the same ratio of meat:veges as on the original dish.
I really don’t like using my hands to eat, even things like seafood.
