I love this idea from re-nest: grow your own sprouts from dried lentils. It looks like it a matter of simply covering the lentils with water and storing in a jar until they sprout. You can use bean sprouts in salads or sandwiches or just eat them on their own.
Apparently, it takes 4-5 days to get your own bean sprouts. According to the site, “you can sprout anything from beans to lentils to garbanzo beans.”
This is a great indoor gardening project, especially if you can’t get bean sprouts in your area during the winter.
