In keeping with the food theme, here's a favorite for camping, works at home too. Break a few eggs in a ziplock bag, add salt, pepper, a little milk, some grated cheese, maybe some veggies. Close bag, squish it all very thoroughly. Drop in pot of boiling water. Poke it around a bit to keep it away from the sides of the pot, it helps to burp the air out as much as possible. Boil 10 minutes. Eat. No pan to wash. Low fat if you care.
