If you’ve got some extra lentils (or other beans) at the bottom of the bag, use them to grow bean sprouts. Put them in a glass jar and fill with water to soak overnight. Then, pour off the water and drain the beans. Sit the jar in a sunny window, and rinse the beans every day. In a week or less, you’ll have homegrown sprouts to harvest for salads, sandwiches, and other dishes.
