Instructions
- Preheat the Oven and Prepare Baking Dish: Preheat your oven to 400°F (204°C) and coat an 8×11-inch casserole dish with cooking spray to prevent sticking.

- Season the Squash: Drizzle the inside of each squash half with olive oil, then sprinkle with salt and pepper evenly.

Stir and heat for about 5 minutes until everything is well combined and warm.
