You know, those delicious dishes that should probably take 10-15 minutes, but you'd much rather make it a 30-60 second process by throwin' it in the microwave. I'll start:
Ghetto Grilled Cheese
Throw two pieces of bread into the toaster, in the meantime, pull out a slice of cheese. Once the toast is ready and still hot, put the cheese in between the toast and zap it in the microwave for 5-10 seconds. Voila!
