Fill a large pot with salted water and bring to a rolling boil. Add the cheese tortellini and cook according to package instructions, usually 3-5 minutes.

In a large skillet over medium-high heat, add oil and sauté chopped onion for 1-2 minutes until translucent. Then, stir in minced garlic for another minute.

Add ground turkey and break it apart with a spatula. Season with salt, pepper, garlic powder, and paprika. Cook for 5-6 minutes until browned and cooked through.

Lower the heat, pour in the marinara sauce, and add Greek yogurt. Stir until smooth and simmer for 2-3 minutes.

Drain the tortellini and gently add to the skillet. Fold in spinach and drizzle lemon juice, ensuring spinach wilts and tortellini is well-coated.

Remove from heat, sprinkle grated Parmesan cheese, and stir until melted. Serve immediately, garnished with extra cheese if desired.
