Very carefully, cut spaghetti squash into 1" - 1 1/2" rounds.
Clean pulp and seeds from center of squash rounds.
Place onto rimmed baking sheet (foil line or use parchment for easy clean up)
Drizzle each round with olive oil.
Sprinkle with salt & pepper.
Bake at 375* for approx. 30 minutes or until squash is fork tender.
Remove from oven.
Using a fork, carefully "strand" the squash so that it resembles spaghetti noodles.
Serve as is (parmesan cheese optional), or with a favorite veggie or meat sauce.
