Have you ever wondered if you could use the inedible parts of food to regrow them? Why take another trip to the grocery store when you could use the products you already have to grow more? It might seem silly, but there are tons of foods that you can easily grow at home. Instead of throwing away the white ends of scallions, put them in water and watch them grow before your eyes. If you put them in soil, the flavor is even stronger. It is like having a never-ending supply of scallions!
