I've taken frozen steak and/or "Cornish Game Hens" for the first night out lots of times. Usually bring a foil wrapped potato to toss in the coals of my campfire to go with them. Frozen breakfast burritos are great too, and they'll last a couple days in my pack if insulated well.

After that I'm using off the shelf dehydrated meals, usually Mountain House. I don't really have a favorite one of those, but they keep me from starving and keep my pack weight down. Oatmeal with dried fruit is always good for breakfast.
