Salvomassara/ShutterstockRinds from hard cheeses like Parmesan make a great base for homemade stocks or as an add-in to homemade soups for extra flavor. Just rinse off the rind, then throw it into a pot of soup or broth once it's simmering. Make sure to fish it out of the pot before serving up the soup!
alexkich/ShutterstockBefore you peel that orange, stop. First, grab a cheese grater to zest the peel. If you don't have an immediate use for it, store it in the freezer in a zip-top freezer bag for later use. "Rather than throwing away that lemon, orange, or even grapefruit peel, I use every piece of it as a zest for marinades, homemade salad dressings, and baked goods!" says Angie Asche, MS, RD, a sports dietitian in Lincoln, NE. "Citrus peels contain vitamin C and fiber, making them both a flavorful and nutritious food scrap."

"It can be used as an egg replacement by whisking the liquid until it is white and foamy, in a homemade vegan mayo when combined with vinegar, mustard, salt, and oil, or as a vegan dairy-free chocolate mousse when whipped aquafaba is combined with unsweetened cocoa powder and melted dark chocolate," she says, adding, "As a bonus, the aquafaba provides nutrients like protein and minerals."

Elvira Koneva/ShutterstockJust because it's not as pretty as the red fruit it's attached to doesn't mean you can't eat the rind!

Kevin Kozicki/ShutterstockYou can find many uses for the stalk of this cruciferous veggie. "Broccoli stalks contain numerous health boosters, including fiber, potassium, calcium, and more," says Samantha Cassetty, MS, RD, a nutritionist in New York City. "Each stalk has more than a day's worth of vitamin C—more than you get in an orange!" Cassetty suggests peeling the outer layer and finely slicing the entire stem. "I then roast them with extra-virgin olive oil and salt on low heat until they're crisp. My son loves to snack on freshly cooked broccoli coins, but I also use them as a salad topper or in a side dish mixed with similarly shaped veggies such as thinly sliced carrots." You can also make a broccoli slaw with the stalks.

Pasta cooking water
Valerio Pardi/ShutterstockThe recipe you're following might direct you to discard the water in which you cooked your pasta. But wait a minute.

This liquid can be immediately added to thicken and flavor pasta sauces. Or freeze it into ice cube trays and throw a cube into stocks or broths, soup, and chili, or gravies and sauces."

Rice cake crumbs

"They provide a refreshing flavor, as well as fiber and beta-carotene, an important antioxidant and precursor to vitamin A. As with so many fruits and veggies, rich nutrients can be found in and right below the skin—so don't ditch the peel when it's so a-peeling."
Nut milk pulp
Vorontsova Anastasiia/ShutterstockAre you a fun of DIY nut milk? Don't toss the pulp. "I love making homemade nut milks, but after tossing the pulp a couple of times I felt there must be ways to use this nutrient-rich substance," says Marisa Moore, RDN, a registered dietitian nutritionist in Atlanta, GA. "Instead of tossing it, you can add it to oatmeal, muffins, or banana bread for extra protein and fiber." For muffin and quick bread recipes, swap up to a quarter of wheat flour for dried pulp, advises Moore. Try using nut milk pulp after making homemade pistachio milk.
