A: Total shelf life is 90 days but actual expiation may differ depending on how long it's been sitting at your local store. All expiration dates are printed directly on each cup.

A: In microwave. First you take out little packages of items wrapped in plastic (potatos, bacon or sausage, onions, etc.), put an egg or two in the empty cup, stir them up, empty the little packages into cup, stir again and cook in microwave according to directions. For 1 egg, I believe it is 30 seconds, stir and cook 40 seconds more. With 2 eggs, I've found that cooking 40 seconds, then stir, then cook 50 seconds works best.
