I have used spaghetti squash before, it's very good. You can replace your regular spaghetti with it and have it with. My favorite way to enjoy it is, once it's cooked, I put a little bit of butter on it and sprinkle some parmesan cheese and pepper. It does take longer to cook than pasta but it is delicious so to me it's worth it. However, it's not something I eat as often as pasta, because even if it is worth it, the pasta is just much more convenient. Plus there's the fact that I'm the only one in the house that eats it.
