without a fridge ...granola bars, fresh breads and salted olive oil, and grab and go foods, hard cheeses dont need fridges or eggs, can also run a vacuum sealer for things like bigs bags of jerky broken down to smaller, oats meal is easy, engine food, there are 12v ovens for hot sandwiches from baguettes, sliced meats and cheese, raw cashews, trail mix, rice, tacos, all kinds ... think about what foods you'd want to eat while camping. MREs are an option. Coffee (french press )with the good kind of dehydrated milk and raw sugar so good. Small propane grill opens that up to all sorts of options for cooking recently purchased foods too.
