Creating Tuscan Chicken and Spaghetti Squash can be simple if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare Spaghetti Squash: Cut the spaghetti squash in half lengthwise. Scoop out the seeds and drizzle with olive oil, salt, and pepper. Place cut side down on a baking sheet.
3. Roast Squash: Roast in the preheated oven for 30-35 minutes, or until the flesh is tender and easily shredded with a fork.
4. Season Chicken: While the squash is roasting, season the chicken breasts with garlic powder, onion powder, Italian seasoning, salt, and black pepper.
5. Cook Chicken: Heat olive oil in a skillet over medium heat. Add the seasoned chicken and cook for 6-7 minutes on each side, or until the chicken is cooked through and has a nice golden color.
6. Add Vegetables: Once the chicken is cooked, add the cherry tomatoes and spinach to the skillet. Cook for an additional 3-5 minutes until the spinach is wilted.
7. Combine Ingredients: Remove the spaghetti squash from the oven. Shred the flesh with a fork and divide it onto plates. Top with the sautéed chicken and vegetable mixture.
8. Garnish: Sprinkle grated Parmesan cheese over the dish and garnish with fresh basil before serving.
