When I went camping last summer I made salads and put them in tupperware containers. I also brought some cheat items that I won’t mention. You can make buckwheat or oat bran pretty easily, the main thing to worry about is cleaning it up or the heat source. If you can make the breads once a week, this should go a long way in helping you out. Chicken sausage is something you can easily cook with a campfire.
