Did you know you can re-grow your romaine lettuce? Yes my friends its true and if your like me you pinch every penny you can, making this a great trick. Next time you make a salad out of romaine save the heart of the lettuce (the very end) and stick it in a cup or bowl. Then add a little water and sunlight and watch the leaves re-grow before your eyes (not instantly of course it takes a few days). Who doesn't love free food!
