When you adopt a zero waste cooking lifestyle, you have to have a plan for your bananas. It’s almost inevitable that you will have one or two overripe bananas left from every bunch you buy. You can use them in smoothies, make a frozen treat, or bake muffins or a loaf of banana bread.
Weekends are a perfect time to bake banana bread. If you notice the bananas ripening during the week, pop them in the refrigerator and make a loaf on your day off.
Using up Commonly Wasted Foods
Dairy tops the list for food waste, and fresh produce is a close second. If you buy plain yogurt by the quart, you might occasionally find yourself with a small portion left in the bottom of the container. If it’s a few days past the ‘best by’ date, you can bake with it. In general you can substitute 1/4 cup of yogurt for an egg, or in the case of banana bread, for one banana.
This version also used up some plain yogurt that I had left and some fresh blueberries and raspberries that were ripening as well. Most banana bread recipes call for 3 bananas, I had 2, so I subbed in the yogurt. Using what you have on hand is the key to zero waste cooking!
