An easy way to prepare is to make sure that some of the food you regularly buy cannot be stored. Crackers are a great vehicle for other things you may have on hand, such as nut butter or cheese. Whole grains will be more satiating. It can always be taken by spoons, in Pb&js, in cookies or with apples.
Cassetty recommends a variety of products that are not only tasty and nutritious, but also foods that you can survive with for an extended period of time. Products such as rice, quinoa, dried or canned fruits and vegetables, a variety of nuts, and canned soups with low sodium content. He also says that canned tuna, salmon and sardines also help maintain adequate protein intake for the quarantine diet. Non-perishable foods (sometimes foods that can be kept at room temperature) are foods of a type that can be safely stored at room temperature in a sealed container.
All of these approaches can extend the shelf life of a food, often without changing its flavor or texture in an unacceptable way.
