There are a few thrifty ways to use the pulp (which is mostly fiber) and reduce food waste. For starters, add some back to your juice or smoothies to reclaim the fiber. It’s also great to save for your compost pile! Or save it for a day in the fridge and add it to other foods. For example, fruit pulp can be added to hot or cold cereals, breads, and muffins, while veggie pulp works in stews, broths, stocks, dips, or sauces.
