Burrito - Refried beans, rice (I prefer brown), your choice of pico de gallo or guacamole. I've also done sauted sweet bell pepper, it tasted great.

Summer Veggie Sandwich - GOOD bread (I like a nice sourdough), hummus for spread, lettuce, tomato, cucumber or squash, salt, pepper, and italian seasonings.

Five Ingredient Chili - Beans (any of black, kidney, pinto, etc), diced tomatoes (canned or fresh), onion, garlic, chili powder. Chop and saute the onion + garlic, then add in everything else and stew for at least 20-30min. Longer is better. Ratio is roughly 2 cans beans, 1 can tomatoes, 1 tbsp chili powder but obviously change as you like. Can also add corn and/or bell pepper (saute first). If you can find a sealed cast iron pot, you can make it all in one pot.

Actually Good Lentil Soup - I've had little success with lentils - they usually turn out 'ok'. This one is actually good. Chop+saute onion, garlic, carrot, and celery. Add 8oz of tomato paste and 150ml of wine (old wine is fine, it's going to be boiled away). Mix well and stir frequently until no liquid is remaining at the bottom of the pot. Add a carton of vegetable broth, 1 cup lentils, and 1 tsp of italian herbs. Bring to boil and simmer ~45min or until lentils are tender.
