It is easiest to do this with dry foods but also possible to "pot" wet cooked meat (hot) then reheat to sterilize. This is most popular with backpackers not car campers because obviously packing a ice cooler much easier and there are more food options available on ice. There are several online retailers that sell many sizes of mylar or plastic bags for about 20 cents to $1 each in various quantities. Here is a youtube video showing one method but it is not the best, there is probably a better video I just could not find one. Best to experiment with something simple like peanuts or noodles first. Oxygen observers only necessary if you are storing for a long time. Extra large bag if you want to add hot water to cook a meal in bag like Mountain House or Backpackers Pantry etc.
Another method is using the extra fat plastic straws and sealing the ends with heat. I have filled these with peanut butter, also Almond, Cashew and other snacks. There are some YT videos of this but its is fairly obvious. These are popular with some triathlon, and endurance racers.
