Not counting all the food made for camping like Mountain House and other freeze dried food. The local grocery store has so much good easily prepared and even already cooked or no need to cook food, I can’t see how a person can not find an almost unlimited choice of light weight food to take camping or backpacking.
Grocery store food is very low cost compared to freeze dried food. You can feed yourself for 3-days on what Mountain House meals would cost for 1-day.
Also don’t forget can food, yea it’s a little heaver but a few cans of pre-cooked food that has to only be heated is nice after a day of hiking. To me it’s worth the weight to have a quick meal that I did not have to work to cook. You can even warm it up in the can to save cleaning up cookware after the meal.
