If you don’t count oip and spices, then any kind of dal. Dal, onion, ginger garlic paste, chili, tomato. Then add your spices, which can be as simple as garam masala, turneric, and red chili powder. Salt after it’s cooked. Aside from the onion everything can come from the pantry or freezer. Technically you could blend and freeze the onion to make life even easier.

I know I’m pushing it but this is basically the easiest meal ever and it’s just one pot. You only need to dirty a cutting board, knife, and spoon. It’s nearly a pantry meal and requires no thought or special technique aside from knowing when onions are caramelized but not burned. And it’s vegan, gluten free, and very inexpensive.
