Steps:

• 1. Preheat the oven to 400°F, line a baking sheet with baking paper and grease a 8x8 casserole dish with olive oil. 2. Cut spaghetti squash in half lengthwise, scoop out seeds, season with olive oil, salt and pepper and place cut-side down on the prepared baking sheet. Bake for 45 minutes, until the skin of the squash is fork tender. 3. While squash is baking, prepare caramelized onions and mushrooms.

Cook onions and mushrooms for 8-10 minutes more, until there is no more liquid in the pan. 4. Remove squash from the oven, scoop out flesh and place in the prepared casserole dish.
