Honestly, when we first started camping we tried to do elaborate meals. (Big breakfasts.. toast, eggs, bacon or pancakes and sausage. Lunches were hot dogs or hamburgers, and for evening meals, steak, onions, mushrooms, hash browns.) Over time, we realized that we were spending too much time with meal prep and clean up, that we would have rather spent on the trail or sitting on the beach.
Now we camp lighter with an 'eat to live' mentality. (Breakfast- bagels and cream cheese, or english muffins and PB. and fruit. Lunches- sandwiches which we can pack right after breakfast and hit the road with, and Dinners are hot dogs, burgers or hobos- foil packs with burger, carrots, potatoes and onion)
