Celebrating National Nutrition Month 2018, “Go Further With Food,” I rounded up 27 Dietitian-Approved Recipes Using Leftover Foods To Reduce Food Waste. This month is meant to bring awareness to people on how to live healthier lives. The theme, Go Further With Food, is meant to encourage people to take their food to the next level. Where we’re not only thinking about healthy food choices, but we’re also thinking about how to correctly reduce food waste, which will also lower your grocery bill. The below recipes use parts of foods we may throw away, such as vegetable tops, green “stems,” or ugly produce. Another way to reduce food waste is planning a menu and preparing meals in advance so you only buy what you need. This can save money, too.

Many of the below links don’t just contain incredible recipes, they also include posts on more examples of how to reduce food waste. Talk about tons of tasty education to go around. Enjoy the fabulous meals and continue to celebrate National Nutrition Month all year long.
