Have you ever started to make a recipe only to find out it had onions in it and prepared yourself for tears? Prepare for tears no longer...meet Sunions.
Usually, after I'm done cutting up lettuce at my house (which, is rare to begin with), I just toss of the stump of the head or toss it outside for the animals.
But next time you have that stump in your hand, maybe you will want to try this instead of just tossing it out.
