I'm pretty lazy when it comes to backpacking food. Most of my meals are just something like Liptons Spanish rice. Dump packet in pot. Add 2 cups of water and stir. Cover and boil for about 7 minutes. Sometimes I add chicken, either from a small can or now from the lighter pouches. With my MSR Whisperlite, I have to use a simmer plate and spacer and fiddle with it. With my Pepsi can stove, I can pretty much just throw it on and the stove holds exactly enough fuel to do the job. It's less efficient, so it doesn't burn the food.

I also use a small Outback Oven with "just add water" brownie, muffin and cornbread mixes. Cornbread and almost any sort of soup makes a solid meal for us. I haven't had the patience for pizza or anything more elaborate.

We usually end up eating instant mashed potatoes or oatmeal at least some of the time because those are pretty simple and easy to clean up. We also eat a lot of GORP, which often is the bulk of breakfast and lunch. A pack of cheese crackers or some jerky makes lunch feel "official".

Clean-up never seems that bad to me, except for the food scraps and animals. I usually unload the food into bowls and dump another cup of water into the pot to boil with some soap. When we're done, I wipe and scrub everything and dump the water into a cat-hole. I rinse about twice. I usually end up using a paper towel too, so I either burn and bury that or now I'm more likely to just pack it out.
