Freezing is fairly easy and rewarding. Tomatoes are ridiculously easy to freeze, for example, I wash them, put them in a gallon bag in the freezer, then remove the skin when I thaw them to prevent peeling. This is perfect for soups and sauces in the winter. Most vegetables need to be blanched before freezing so do some research on what you’re freezing and make sure it doesn’t end up going to waste.
