When I was a teenager: open a can of Campbell's chicken & rice soup. Skim off fat. Eat soup with a spoon. No cooking, no washing up (except the spoon) and no time wasted heating it.

Boil pasta in salted water until it doesn't crunch. Drain, and stir in Cheeze Whiz. (For anyone who's unfamiliar with this, it's a cheese-like food-like product in a jar.)
