I need food I can comfortably live off without a car, stove, oven, pots, and pans.

So far my diet consists of:
PB&J, chicken and tuna sandiwches (store-brand bread, lettuce, cheese, tomato, onions, mayonnaise), ramen (with or without eggs and or cheese), bananas, and cereal.

I use to eat strawberries and grapes, but they're too expensive.
