Maybe this could go under the heading of foraging in your refrigerator :-). I saw this cool idea and thought I would try it. I noticed that sometimes when I put things like celery bottoms in the compost pile that they would continue to grow. Well the same thing can happen with other veggies and green that still have a portion of the part that sits right at ground level left on them, like romaine lettuce. So here's what you do. Eat all the lettuce that is on it and then put the stump that is left over in a glass of water. Here is my little indoor lettuce garden made from the throw away part of the lettuce that I bought at the store. Cool, huh?!
