Preheat oven to 400°F. Rub spaghetti squash halves with 1 tablespoon olive oil, sprinkle with salt & pepper and place on a baking sheet cut side up. Roast for 30 minutes, flip squash and roast for another 30 minutes, or until tender.

Meanwhile, heat 2 tablespoons olive oil in a medium saucepan over medium high heat. Add a pinch of red pepper flakes and garlic, cooking for about a minute.

When the spaghetti squash is done, let cool for 5 minutes. With a fork, shred the meat of the squash and place it directly into the pan of mushrooms. Add the Parmesan, parsley, basil, and remaining tablespoon of olive oil. Stir well to combine. Season with salt & pepper and serve.
