In a large skillet with a lid, heat 2 tablespoons olive oil. Once hot, add sausage and cook until well browned, about 3-4 minutes per side. Add garlic and stir until golden and fragrant, about 30 seconds. Stir in broth, tomato sauce, cream and tortellini. Cook until simmering and bubbly. Reduce heat to low, cover and simmer for 12 minutes, or until tortellini are tender and heated through.
Serve and garnish with chopped parsley, if desired.
