1 tablespoon olive oil

2 cloves garlic, minced
1 bell pepper, diced
2 cups fresh spinach
1 cup cherry tomatoes, halved

1 teaspoon chili powder
1 teaspoon cumin
Salt and pepper to taste
1 ½ cups shredded low-fat cheese (mozzarella or cheddar)

How to Make Healthy Spaghetti Squash Casserole Step-by-Step

Step 1: Preheat your oven to 400°F (200°C).
Step 2: Prepare the Squash: Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle with olive oil and season with salt and pepper.
Step 3: Roast the Squash: Place the squash halves cut side down on a baking sheet. Roast in the oven for 30-40 minutes, or until tender and easily pierced with a fork.
Step 4: Sauté the Vegetables: Heat a skillet over medium heat. Add the diced onion and sauté until translucent, about 5 minutes. Add garlic and bell pepper, cooking for an additional 3-4 minutes.
Step 5: Stir in the spinach and cherry tomatoes. Cook until the spinach wilts, about 2-3 minutes.
Step 6: Add the black beans, chili powder, cumin, salt, and pepper. Stir to combine and cook for another 2-3 minutes until heated through.
Step 7: Once the spaghetti squash is done roasting, use a fork to scrape the flesh into a bowl, creating spaghetti-like strands.
Step 8: In a large mixing bowl, combine the spaghetti squash, sautéed vegetable mixture, and half of the shredded cheese. Mix well.
Step 9: Transfer to Baking Dish: Pour the mixture into a greased casserole dish. Top with the remaining cheese.
Step 10: Return the casserole to the oven and bake for an additional 15-20 minutes, or until the cheese is melted and bubbly.
Step 11: Let the casserole cool for about 10-15 minutes. Garnish with fresh basil if desired before serving.
