If you get an Instant Pot the 7 in 1 IP-DUO60 one, you can use it as a small oven (big enough for a whole chicken), stove top burner, slowcooker, rice cooker, yogurt maker, sauté pan, etc.

It would make it possible for you to cook most things. In many cases, you could make a well balanced one pot meal in it. In other cases it would be necessary to cook one dish at a time and refrigerate or freeze portions, then go on to dish two or three.
