You don't mention whether you're camping in a tent or a KOA
If you have one of the cabins, you have a few additional options
available to you that you may not have considered. There's an
outlet or two in the cabin, so you could plug in an electric kettle
to boil water -- perfect for instant soups, tea and/or coffee, hot
cocoa, instant oatmeal and/or grits, etc. If you have any of
those "just add water" dishes, like freeze dried camping food or
Lipton rice mixes, you'll have the hot water needed to prepare
those as well.
I have been known to bring a small electric rice cooker with me
when camping in a cabin. I've cooked coconut rice pudding in
one (use coconut milk instead of water, add sugar to the coconut
milk and rice mixture, stir, cook, add fresh or canned or dried
fruit when serving), breakfast "fried rice" (measure out usual
proportions of rice and water, add soy sauce, white or black
pepper, a little sugar, some dehydrated veggies, and garlic powder,
let cook until rice cooker switches to "warm". While rice is
still hot, quickly mix in beaten egg and precooked bacon pieces.
When egg is cooked, serve), and even soup or stew.
There's also things like PBJ, lunch meat or tuna sandwiches,
hummus and pita chips and/or veggie sticks, taco salad (prepare at
home, add taco chips to bowls just before serving -- adding them at
the last minute to individual servings keeps them from getting
soggy), muffins, bagels, trail mix, etc... you get the idea!
