Cook the pasta of your choice according to package directions.
Break sausage into small pieces and add to large skillet.
When sausage begins to brown, add vegetables (with additional oil if needed). If you're using onions, add them first, then harder vegetables like carrots. Quicker cooking ones like bell pepper and tomatoes can go in a little later. Add garlic when the last vegies go in. Stir frequently and cook until vegetables have reached your preferred doneness.
Season to taste with salt, pepper and parmesan cheese and serve over pasta.
