Heat olive oil in an oven safe skillet. Crumble in sausage and cook through, until no longer pink.

Stir in spaghetti sauce, Italian seasoning water, and tortellini.

Bring mixture to a boil, turn heat down to low, cover and simmer for about 8 minutes or until tortellini is tender. While pasta is cooking, turn broiler on to low (optional).

Remove from heat. Sprinkle mozzarella and Parmesan evenly over tortellini.

Place pan under the broiler for 2-3 minutes until cheese is melted. Alternately, you could place the lid back on the pan and let the heat from the pasta melt the cheese.
