Wife and I did all the cooking this past Yosemite trip, we had 16 people in camp.
Used a Campfire Cheff grill and 2 burner Coleman to get it all done with ease. We always cooked enough to fill an aluminum half pan, was never short on every having seconds or more.
Breakfast
Scrambled Eggs, Bacon, Tater Tots and Oatmeal, Coffee.
Dinner
Smart Final 30 box of beef patties, 2 big packs of Hoffy large wieners, one large can Hormel chili, sliced cheddar, condiments, 1 ice burg lettuce, Beer
Breakfast
Scrambled Eggs, Polska Kielbasa, grilled onions and green peppers, and pancakes, fresh sliced strawberries, Coffee.
Dinner
Spaghetti w/Meat sauce, ground beef added, Costco bag of Meatballs, Green beans, Dinner rolls (some toasted with garlic butter), Beer
Breakfast
Chorizo Scrambled Eggs, homestyle potatoes, Arroz con Leche, tortillas, Cafe de la Olla.
Dinner
Round Tip sirloin chuck, sliced up, cooked with onions and green peppers, tortillas, Beer.
All meat we kept frozen in a single ice chest that had dry ice on top, nothing else but meats in here.
Eggs were all 50 count boxes from Walmart, cheap, easy storage.
Everything was bought at Smart n Final (Could do same from COSTCO)
The Camp Cheff grill is strong, use griddle on one side, pans and pots on other. Used the Coleman for smaller pots, heat water, etc.
The main trick we have learned, is keep the meal menu simple, use the items that will spoil or get smashed (bread, buns) early in the weekend, dry goods go last...
A couple good items are super tasty when you're hungry and there is enough for everyone vs variety. Special diets, well not my problem LOL
