Any prepper plan has to take into consideration what food options will be best in various situations. Usually we recommend different types of food for different scenarios. If the power goes out you look for food that doesn’t need to be cooked. Canned tuna, MRE’s and snack bars fall into this category of course so do a lot of other foods. You want to store foods that your family will eat but there is also a need to have long-term storable food that you can take with you in a bug out bag. Frequently I will recommend freeze-dried foods for bug out bags, but those do require some preparation. For starters they need hot water or else you are eating rocks. MREs do not need water (except the pudding) and you don’t even need to heat them up.
Though its light weight and long shelf life are ideal for navigating harsh conditions, freeze-dried food is probably most famous as a cultural curiosity: Like many Americans, I discovered it in a museum gift shop, gawking at the styrofoam-like ice cream that astronauts used to have for dessert. More recently, I encountered it at a disaster preparedness convention in Raleigh, North Carolina, where smiling, gray-haired preppers manned tables piled with plastic bags full of vegetables, meats, and stews.
