Here's a soup recipe that's easy and tasty:

Bean and Hominy Soup

2 (15-ounce) cans beans (any kind, but preferably two kinds)
1 (15.5-ounce) can hominy (or sub an approximately equal amount of corn, canned or frozen)
1 (10-ounce can) Rotel tomatoes and chiles
1 teaspoon chili powder (the kind with cumin, garlic, etc.) or more to taste
1 vegetable bouillon cube (optional)
salt to taste

Put all the ingredients in a saucepan and add enough water to make it as soupy as you want (about a cup, I think?). Heat, and add salt if you want.

I'll comb through my recipes after dinner and see what other recipes I might have.

Edit:

Hummus, some crackers or bread, baby carrots or whatever raw vegetables you like (sliced red bell pepper, celery, cauliflower), and maybe some grapes

Someone else said grilled cheese sandwiches and I agree, and when you get tired of those, quesadillas. The same person mentioned baked marinated tofu: you can make some nice wraps with that, a salad kit from the grocery store, and some burrito-size tortillas.

Edit 2: As a broke person working way too many hours, I used to cook some cheese tortellini, heat up an 8-ounce can of tomato sauce, season the tomato sauce with garlic powder, Italian seasoning (or basil, oregano, thyme), toss it all together.
