With the upswing of the prepper community, it is easier to find freeze-dried food. I have found it easier, and cheaper, to buy a can of individual ingredients and then combine them in a freezer bag. Of course, I also live in a state where I can walk into any major grocery store and find #10 cans of freze-dried food. OM, all the freeze-dried peas that I have tried have turned out really yummy. Not as good as frozen, but much better tasting than canned. Of course, fresh peas are like candy...except I can eat a whole bunch and not get sick.

One of the things I have tried and liked is freeze-dried chicken with instant rice, and freeze-dried vegetables. I will also throw in some seasonings.
Here is what I bought last time. freeze-dried chicken
It looks expensive, but I bought it for a group, and it came out to be about a dollar a meal for the chicken, which is about the same as a small tuna packet, and that was with the same amount of calories.
