Follow these simple steps to create your Turkey Meatballs with Pumpkin Sage Sauce:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Mix Meatball Ingredients: In a large mixing bowl, combine the ground turkey, breadcrumbs, Parmesan cheese, parsley, garlic, egg, salt, black pepper, oregano, and onion powder. Mix well until all ingredients are thoroughly incorporated.
3. Form Meatballs: Using your hands, shape the mixture into meatballs, about 1 inch in diameter. Place the meatballs on a baking sheet lined with parchment paper.
4. Bake Meatballs: Bake the meatballs in the preheated oven for 20-25 minutes or until they are cooked through and golden brown.
5. Prepare the Sauce: While the meatballs bake, heat olive oil in a large skillet over medium heat.
6. Add Pumpkin: Stir in the pumpkin puree and cook for about 3-5 minutes until heated through.
7. Add Broth and Cream: Slowly add the vegetable or chicken broth and heavy cream to the skillet. Stir until combined.
8. Season Sauce: Add chopped sage, salt, and pepper to taste. If desired, add red pepper flakes for a touch of heat.
9. Combine Meatballs and Sauce: Once the meatballs are done baking, gently add them to the pumpkin sage sauce. Simmer for about 5-10 minutes to allow flavors to meld.
10. Serve: Remove from heat and prepare to serve your delightful dish.
