For me, they usually involve cheese on some kind of starch plane, heated in the microwave. Currently, it’s mozzerella on rice cakes, with garlic powder and cayenne pepper.
What do you throw together to snack on when there’s not much to eat in the house, and you’re too lazy to go to the store?
Put 2 pieces of bread in the toaster and toast them. The instant they pop out, put a slice of reduced-fat (NOT fat-free) American cheese on one piece of bread and cover the cheese with the other piece of bread, i.e. make a sandwich out of it. Put the whole thing in the microwave for 30 seconds, and bingo! Instant grilled cheese sandwich, and you didn’t even have to use any butter.
