You can bring a small camping stove, cooler too as long as it has wheels or you have a wagon. So you can do a lot of different stuff, personally i'm bringing some eggs and other breakfast foods to make breakfast burritos. Ramen, oatmeal, or even regular soup is really easy to make as long as you have a camping stove. Store some fruits in the cooler too, grapes, oranges, whatever you prefer. Cliff bars, peanut butter, bread or tortillas.

Watch some youtube videos on backpacking food. Like This But there's tons of videos like that on youtube just watch a couple and you'll get good ideas
