My favorite camping breakfast is kippers on bread with some hot water to wash it down.
My lunches usually consist of bagels or tortillas with either peanut butter or some kind of canned meat.
For dinner, Hawk Vittles is the way to go.
I'm not crazy about Mountain Houses -- my first experience was with the lasagna and meat sauce -- it was easy to prepare and tasted great, but gave me unbelievable gas. My sleeping bag has not quite smelled the same since.
I'm willing to go light in terms of food when I backpack. I usually stick to mixed nuts and fruit during the hike, and some high quality jerky at day's end. I've read that making one's own trail mix and jerky is manageable - I think I'm going to try it.
