There are plenty of things you can buy or cook and freeze in your freezer to save a couple of bucks. This includes the more expensive ingredients like cheeses and other fussy ingredients like ginger that quickly go soggy. You can also store tomato sauces or pasta sauces you've made in bulk. You can even buy a whole loaf of bread and stash them in the freezer, and toast it when you want to consume it. Vegetables like citrus and spinach in the freezer are a lifesaver for college-going young chefs.
