When I go camping, I do almost all my cooking on a little alcohol stove, they don't take special fuel, any gas station will have the yellow Heet that you can use for fuel in it.

But what I usually eat:

• Canned soups, can be made hot right in the can, but heavy if you are backpacking.
• Oatmeal and instant noodles like ramen just need to heat some water.
• Those microwavable rice pouches, just need to heat them up, I also like to add some tinned mackerel and some hot sauce with it.
• Bagels, eggs, spam, and cheese makes bomb breakfast bagels. Cheese and eggs will last a couple days. Eggs that are not washed do not require refrigeration.
• You can also bring some cured meats if you want to make sandwiches on your first day. Some meats like summer sausage don't require any refrigeration so will last until you cut into the casing before you need to worry about it. I also will stop at a gas station and grab a few of the single use packets of condiments: mayo, mustard, bbq, relish, etc.
• And MREs or freeze dried meals are easy.
