I've got a full nesting set(purchased at Target) I carry in my ruck, plastic cup inside small pan inside larger pan topped off with a small frying pan, there's room in and around the cup for salt/pepper and about a dozen boullion cubes. With this small cook kit, even if I lose or use up my carried food, I can make a decent meal from scrounged greens & tubors, and maybe the occasional rabbit or squirrel. I've also got an issue canteen cup between a canteen and cover, but since I've gotten the cook kit, all the cup gets used for is morning and evening coffee.
