If you used takeout containers and Tupperware to house every half an onion and three-quarters green pepper that wasn't used in dinner prep, you might run out of storage for your actual leftovers—and, over time, usable shelf space. But, you'll run through box after box of plastic baggies by saving food scraps for future use. This four-piece set of CoverBlubber® food-saving wraps, though, cling to the ends of nearly any fresh-cut fruit or vegetable, open can, or bowl so that each takes up no more space than the food itself. (Plus, they're all BPA and Phthalates-free!) Available on Uncommon Goods; $20.
