I travel light, mailnly because I camp with my motorcycle. only camped in the truck once. For cold stuff, I only carry a soft-sided cooler and deploy all the cold items within the first 24-48 hours, unless it's cold outside.
My usual:
Breakfast choices
Powdered eggs, home-dehydrated mushrooms, scrambled together and Hormel real bacon bits (in a jar) added in at the end.
Shake & Pour pancakes, real maple syrup, hash browns, pile of bacon bits.
Instant oatmeal or farina
Lunch choices
Zatarain's gumbo, jambalaya, dirty rice & chicken, etc from a pouch, or other brand soup, rice, chili, etc in a pouch, heated on my motorcycle engine over a 200 mile ride.
If I eat lunch in a camp setting, i boil the pouch in my mess kit pot.
Tuna from a pouch and crackers or bread
Ready-to-serve soups in a can, with the can boiled in a pan of water.
