RE: Camp food
We usually do not freeze food already prepared but sometimes we do. The machine you are mentioning is a vacumm sealer. They do come in handy as you can freeze in the bags and throw them in boiling water to cook it. We eat anything with protein and carbs. So anything with meat and noodles. Spaghetti being number 1 on the list but you threw that out.
You will be so tired at the end of the day that you will not want to cook so taking frozen meals is a smart choice.
