Frozen fruits and veggies have the same amount of nutrients, but will last longer than fresh. Canned or dried beans and legumes are nutritious and can be made into a ton of different soups and stews. Stock up on your preferred cooking broth: vegetable, chicken, or beef. Dried pasta is always a good bet, since it can be a delicious meal on its own or added to soup or stew. You probably already have a few cans of tuna, salmon, or sardines, but if you like canned fish this can be a great way to liven up a salad, sandwich, or pasta dish.
