In a frying pan over medium high heat, cook the sausages until no longer pink inside. Remove to cutting board and let rest for 5 minutes before slicing into coins.
Add uncooked tortellini, spaghetti sauce, pepper rings, sausage coins and half of the mozzarella cheese to the baking dish. Stir to combine and cover with foil.
Bake in the oven for 20 minutes. Remove foil and sprinkle with remaining cheese. Then bake for another 10 minutes. Let rest for about 5 minutes before serving.
