Preheat the oven to 350 degrees F. 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.
“The flesh of spaghetti squash comes out in long strands, very much resembling the noodles for which it is named. In this recipe, the ‘noodles’ are tossed with vegetables and feta cheese. You can substitute different vegetables, but be sure to use ones that have contrasting colors.”
