Ingredients

• 2 medium spaghetti squash
• Olive oil
• Salt and freshly ground black pepper, to taste
• 1 cup marinara sauce
• 1 lb prepared meatballs
• 1 cup shredded mozzarella cheese

Instructions

1. Preheat the oven to 400°F (200°C). Line a rimmed baking sheet with foil and lightly coat with nonstick spray.
2. Using a small, sharp knife, carefully pierce each spaghetti squash several times on all sides. Microwave for 3 minutes, turning once, to soften slightly.
3. Cut the squash in half lengthwise and scoop out the seeds with a spoon. Place the halves cut-side up on the prepared baking sheet.
4. Brush the flesh lightly with olive oil and season generously with salt and pepper.
5. Roast for 50–60 minutes, or until a knife slides easily into the thickest part of the squash. Remove from the oven and let cool for about 10 minutes.
6. While the squash roasts, prepare and heat the meatballs according to package directions or your preferred recipe.
7. When the squash is cool enough to handle, use a fork to scrape and fluff the flesh into spaghetti-like strands.
8. Top each squash half with 4 meatballs, about 1/4 cup marinara sauce, and 1/4 cup shredded mozzarella cheese.
9. Place under the broiler for a few minutes, until the cheese is melted, bubbly, and lightly golden. Serve warm.
