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
