Standard chip “spice” here is hot. Here in Cape Town, it would be not quite Indian spice, rather Cape Malay spice, but similar. “Masala chips” or “spice chips” would be the order (the default is still salt and vinegar)
Actually, yes. I read a lot of British novels and I’ve run into a “bacon butty”, and given that background, I’d have correctly guessed what chips were, too.
I need some textural contrast in my sandwiches, and I really like something fresh. I could probably only down one of those things if there were some cucumber, pickled onions, carrots or something like that in it. Otherwise, it’d probably suck all the saliva out of my mouth.
Maybe some nice tart pineapple? 
If a long roll is sliced open length wise, or a round roll sideways, to a depth of at least 38.75%+/-4% of it’s major diameter, it effectively has converted into two pieces of bread to make a sandwich. Otherwise it is a stuffed roll, or possibly a mess.
Speaking of roll sandwiches, how about egg/spring rolls? A case could be made that the wrapper is a kind of bread.
I say no: that’s breading, not bread.
I think anything completely surrounded by bread is not a sandwich, which rules out burritos, wraps, egg rolls, calzones, and hand pies.
Whether an egg roll wrapper is bread would require a whole new level of pedantic discussion - what exactly is bread?
Off the top of my head, I would say bread be composed primarily of flour, must have a crumb, and must not be a cake. But ah, what is the difference between bread and cake? Well, I would say… (and so on).
Defining bread as a non-cake, flour-based baked good with a crumb rules out wraps but also rules out crackers (which have no crumb).* And Rabbi Hillel famously created an ur-sandwich using matzoh rather than bread. So my definition immediately fails and I’m back to square one.
*Or does it? You can certainly make a cross section of a cracker. We’ll have to inception ourselves down another level and determine exactly what a crumb is.
Breading IS bread. It’s in the name. Which means chicken nuggets and chicken fried steaks are also sandwiches.
Breading is bread in the same sort of way that tuna salad is a fish.
So I assume you believe that icing IS ice, and you would put it in your lemonade.
Strawberry icing, sure. Can’t beat strawberry lemonade.
This is perhaps the time to mention that my son is of the opinion that all foods can be lumped into one of salad, sandwich. Here are some critical references:
(see especially appendix B)
For me, it’s because you can’t un-ruin a pizza with pineapple. If we’re sharing a pizza and I get a slice with mushrooms, no problem I just pick them off. With pineapple, you can pick it up but it still leaves the pineapple stench behind. If I’m not sharing it with you, knock yourself off. Put triple pineapple on it for all I care. If I’m sharing with you, then just put it on your half and we’re cool.
In Manhattan, and Israel of course, you can get an “Iraqi sandwich” with fried eggplant, boiled egg, salad, tahini (plus hummus if you want), parsley, and, not pineapple but mango chutney.
ETA chips, pickles, etc are available
Green olives are delicious on a pizza. But pizzerias in most locales do not offer them at all.
You can get black olives, but those are Satan’s boogers. 
Black olives on pizza. Green olives in martinis.
Well, I like pineapple, but there are a lot of toppings I feel that way about. I don’t really want to sit near you if you have peppers on your pizza. But I don’t go around saying that no real pizza has peppers on it, I just say that I don’t like peppers on pizza.
So how do we feel about Marseille pizza? Emmental, black olive and anchovy. Personally I think pineapple would work with that to cut all the salty.
That sounds good to me; Marseille pizza on its own, as does adding some sweet to counterbalance. But I might go even more salty, too, and add capers (essentially, we have tapenade ingredients there) and hot peppers (now we’re in puttanesca territory.) It all sounds good.
Since we’ve all gotten away from the original topic, does anyone remember slivered almonds on Hawaiian pizza? I’ve worked at 3 different pizza restaurants but I’m almost positive I’m remembering it being Showbiz that offered it. Which is a bit weird since almonds are kind of expensive and it doesn’t seem like the best thing to offer at a place designed for kids. I scanned the thread but didn’t see any reference, yet I have a very specific memory of making them(I think).
