Not that we have many leftovers in my house, but when we do, it is nice to find a product that makes storing leftovers easier! Kuhn Rikon Magic Covers ($18 for two at Amazon.com) is a reusable silicone lid that fits over plates, and bowls. Just press down on the center to get a tight seal, that keeps the food fresh in the fridge or the freezer. It is great for pre meal prep and food storage for the week. I highly recommend this product, and know that it keeps lettuce fresh for a week!
