Mayo Clinic has put together a 3-day, 4 person emergency meal plan using shelf-stable ingredients and requiring no power. (The first recipe requires you to cook and refrigerate ahead of time). Not bad eating, during an emergency, I think.
Don't forget the flashlights, batteries, water, manual can opener, paper plates, plastic utensils, plastic wrap, wax paper... You'll also need a couple of mixing bowls, a knife, and a cutting board.
Most of the items on the shopping list can be stored for an extended period of time, while a couple of items like pita bread and tortillas are perishable.
