Smoked Sausage and Tortellini Skillet

Preheat the oven to 350 degrees F (175 degrees C).

Heat a large 12-inch oven-safe skillet over medium-high heat and add smoked sausage. Cook until brown. Add garlic, onion, and bell pepper. Lower heat to medium and stir until vegetables are soft, about 5 minutes.

Stir in cooked tortellini, marinara sauce, 1 cup cheese, and oregano.
