Dry uncooked rice and beans would actually be better.
I am currently living alone [hubs is at the other house] and my ‘normal’ 2 week grocery loadout is something like 5 pounds taters, 5 pounds onions, the large 5 pound bag whole carrots, a 2 pack of celery [not the hearts but the full sized ones] 2 cabbages [1 green, 1 red] 2 napa cabbages, 2 daikon. I also go through the 10 pound sack of all purpose flour, and while I do have 5 pounds of boneless skinless chicken thigh and 10 pounds of ground beef [some is in burger form, some is just frozen in half pound lots] one of my main meats is cheap bacon - I tend to go through 4-5 pounds in 2 weeks, have a batch of ritschert in simmering flavored with bacon right now =)
I don’t actually have a copy of my grocery reciept on hand this instant, but I think I might spend something on the order of 40-50 bucks for 2 weeks of groceries [especially if I need paper towel or toilet paper also]
I suppose if only having like $20 for most of a month’s groceries [which I have been in the position of once or twice in my life =( ] then I would consider ramen bricks, if nothing else, they are intensely flavored. [well, given I purchase the jugs of freeze dried veggies to be used in ramen, I suppose I oculd actually use raw veggies other than the convenience. I miss the days back in the 80s when the cup o noodles I bought had little chunks of dehydrated meat [beef or chicken usually] dehydrated scrambled egg chunks AND a few tablespoons of corn, carrots, shredded cabbage and spinach? Some green leaf you see bits of floating around. So, I buy the dehydrated veggies to augment my ramen [I buy the kind that is in a black rectangular plastic ‘bowl’ peel the top back, fill to the line and add the squeeze packet of teriyaki sauce]
I just find knowing how to cook from scratch tends to make my grocery money go further - I can crank out a couple liters of bacon veggie soup with 1/3 package bacon chopped, 2 ribs celery, 2 carrots, 6 napa leaves shredded, 1 onion the size of a tennis ball and 2 russet potatoes each the size of a fist. Flavor it with a few shakes of black pepper, ditto salt and a teaspoon or so of dehydrated italian seasoning and a bay leaf. Add to it a loaf of bread made of 4 cups flour, a tsp and a half of salt, about the same of yeast and water, and that is 2 meals for adults or a meal for an adult and 2 children
