Onions don’t need much of an explanation, as they are pretty ubiquitous. That being said, if you have never made caramelized onions, here is a good how-to guide. These are great as a pizza topping, and you can throw in some tatsoi, or other leafy green, at the end of cooking. Once the greens start to wilt, your pizza topping is ready! You can also freeze them if you end up making a large batch, which is a good way to preserve onions. For more suggestions on how to use them, see links at the bottom of the how-to guide, or click here.
