Preheat your oven to 375°F (190°C) and grease a 9x13 casserole dish.

Cook the cheese tortellini in boiling water according to package instructions until slightly underdone, then drain and set aside.

In a skillet, brown the ground meat, drain excess fat, then stir in marinara sauce and seasoning, simmering for 5 minutes.

Combine softened cream cheese, sour cream, and shredded mozzarella in a bowl until smooth, then fold in the tortellini.

Spread the tortellini mixture in the casserole dish, pour meat sauce over it, and top with remaining cheeses.

Cover with foil and bake for 20 minutes, then remove foil and bake uncovered for an additional 10-15 minutes until bubbly.

Allow to cool for 5 minutes before serving, and garnish with fresh herbs if desired.
