A discussion we had at lunch today...

What leftovers in the fridge are you willing to eat and for how many days after it's been put in there? What is your personal lifecycle for: Pizza, Chinese Food, Chicken, Burgers, Spaghetti, Birthday Cake, Pie, Tuna, Egg Salad, Meatloaf, Soup, Stew, Turkey and what else?!?!?
