Red lentil, yellow lentil, black lentil, urad lentil, chick peas (white and black), kidney beans, rice, tofu, potatoes, canned tomatoes, coconut cream and prefried dried crispy onions. With those I can make a large variety of foods and sauces. Usually just adding some other veg like peppers, carrots, leaks, etc

Edit: I forgot to list Tamari and Marmite. Good for various things, but combine those in proper proportion withan fried onion base and a flour roux, you have a beefy stew base or brown gravy

Eggs, cheese (mostly cottage), beans, greek yogurt (store bought or homemade), tomatoes, garlic, olive oil, sardines and whatever veggies and fruits are on sale. Same for meat, poultry or fish except the inside organs. For carbs I use corn tortillas and quinoa sparingly because I have to watch glycemic index. For snacks I like popcorn, hummus, pita chips. These are also limited.
