What three dishes could you live on for the rest of your life?
Hm, it said "dishes", not specific foods, so I guess I can have more than one food per dish?
Sandwiches - I mean, talk about covering a lot of ground. What can't you put in a sandwich?
Pancakes and fruit - either topped with fresh strawberries or with some fruit (peaches, grapefruit, apples) on the side, or cooked with berries baked into the pancake. (You could even make chocolate chip pancakes!)
Omlettes, Denver omlettes would have ham and peppers, or a mushroom omlette or you could fold in some nice sirloin steak... yeah, omlettes would cover about everything... :D
