I make pretty much all my own food, it started primarily out of necessity to eat healthy due to high blood pressure.
For breakfasts, I put Bobs Red Mill Muesli, powdered milk and butter, dehydrated fruit and hemp seeds, just add some hot water and its a good breakfast. Sometimes I will substitute the Muesli with instant oatmeal. Typically with add-ins this comes out to 600-650 calories
For lunches, I really like the tuna pack in olive oil, with a sandwich pita, or a couple peanut butter packs with a pita. Dried fruit and nuts.
I like making my own energy bars. Just throw some dates, nuts, dried fruit, dehydrated meat, dark chocolate into a food processor with a little honey or peanut butter. Press them into a silicone bar mold (amazon or Michaels sell them) then vac seal.
Homemade jerky is a must on my hunting trips
Dinners are dehydrated meals I make; I like doing a hearty venison stew with instant mashed potatoes. I do a spicy indian chicken and rice dish thats awesome. My wife makes delicious venison chili mac which always makes the rotation.
All in all, I shoot for about 3000 or so a day. I have found by doing it all myself, an added benefit is that it saves weight and space when compared to commercially packaged stuff also.
