Skip the packaged produce. If you find yourself with three peppers in a cellophane bag or prerinsed salad mixes in plastic tubs in your grocery cart, put them back. The prewashed produce may seem convenient, but pound for pound those items cost way more. And given the recent news that prewashed mixes aren't necessarily clean, you may find yourself washing the food again anyway. Invest in a salad spinner to save money in the long run. Plus, you'll know exactly how your baby spinach salad was washed before you serve it for dinner.
