1. Regrow Veggies.
Strange but true: Scallions will regrow from their white ends. Just put them in a glass of water and let them get some sunlight. You can snip the green ends every few days for practically endless seasoning.

It can be hard to finish a whole gallon of milk before it expires, but don’t wait for it to curdle. Instead, set some aside and make cottage cheese.
