In a saute pan, heat some olive oil. Add a diced onion. Put the squash in and saute the squash and onion together until tender. It doesn't take very long- just 5-10 minutes. Add some dried basil (maybe a teaspoon or two) OR basil pesto (can be store bought. I freeze it in ziplock bags, then break off a chunk and put in with the squash) and a handful of parmesan cheese. Stir well and serve when cheese is melted. This is a yummy and healthy sidedish.
