1/2 cup grated Parmesan cheese
1/2 stick butter
Salt and pepper
Use a paring knife to prick squash all over. Place in a baking dish and bake 1 hour or until soft. Cut squash in half. Scoop out and discard seeds. Using a fork, scrape flesh in strings into a serving bowl. Toss with Parmesan and butter and season to taste with salt and pepper.
There are a few others that use spaghetti sauce. Hope you like it!
