Alternatively, you can use the greens in a soup.
Our family loves
this Kale and White Bean Soup recipe. We use carrots and greens from the CSA box, home-made chicken broth, cook dry beans in a rice cooker and chicken & cheese sausages from Costco. It's way more economical than the Whole Foods version and incredibly tasty.
We cook about 2-3 times the amount of beans required for this recipe at a time. We store the excess beans in the freezer (after they have cooled to room temperature). A few nights before we want to make this recipe again, we move the beans and chicken broth from the freezer to the refrigerator to thaw.
This is very energy efficient. A full freezer uses less energy than an empty one. Every time you open the freezer, you let out cold air and replace it with warm air. A full freezer will have less air exchange.
When you thaw frozen foods in the refrigerator, your refrigerator becomes an icebox! You recapture the energy used to freeze the food.
