Stock or Broth
Soups and casseroles are great options when you're trying to eat on a budget or feed a family. The leftovers also freeze easily, which makes them ideal for stocking up on single-serve portions for later. If you can't make a stock yourself, canned and boxed are must-haves for your kitchen pantry. You can use the stock in place of water when cooking to add flavor to your favorite dish; for instance, try cooking your rice in chicken broth next time.
Stocks and broths come in a variety of options, and packaging, so grab a few of each (chicken, beef and vegetable). There's not much difference between boxed or canned except boxes are resealable, which is great if you don't plan on using all of it at once. However, cans will probably last longer in your pantry than boxed broth.
One thing to keep in mind about stocks and broth: They tend to be high in sodium. So opting for low-sodium or no-salt options is a good idea, especially if anyone in your household is on a restricted sodium diet.
