1. Heat olive oil in a large skillet over medium-high heat. Add ground beef and Italian sausage, breaking them up with a spatula. Cook until browned, about 6–8 minutes. Transfer to a plate and set aside.

2. In the same skillet, reduce heat to medium and add butter. Once melted, stir in minced garlic and cook for 1–2 minutes until fragrant.

3. Add spinach to the skillet and sauté until just wilted.

4. Pour in the heavy cream and stir well. Let simmer for 2–3 minutes, then stir in Parmesan cheese until melted.

5. Meanwhile, cook tortellini in a pot of salted boiling water according to package directions (usually 3–5 minutes). Drain and add to the sauce.

6. Return the cooked beef and sausage to the skillet. Gently toss everything to coat the tortellini in the creamy sauce. Let it heat through for 2–3 more minutes.

7. Season with salt, black pepper, and red pepper flakes if using. Serve hot with extra Parmesan on top.
