Bananas

Don't throw away brown bananas, throw them in the freezer! They defrost quickly when you're ready for them (about 30 minutes on the kitchen counter) and are perfect for making banana bread, muffins, smoothies, and anything else requiring bananas.

Fresh Ginger

Fresh Ginger is super delicious when added to stir-fry, meats, soups and all kinds of things. You can buy a fresh ginger root at the grocery store very inexpensively. I grate off what I want and then store it in the freezer in a plastic bag. Each time I need some, I just pull it out of the freezer and grate some more off. It works splendidly and now I always have fresh ginger when I want it!
