To the now empty pot, add olive oil. Add onions, garlic and cook for one minute. Add sausage and sauté until cooked. I used already cooked sausage so I just needed to heat it up and get a little golden. Add chili flakes and broccoli (fresh or frozen). Stir and cook covered until tender. Uncover and add tomato sauce and pasta. Stir well. Add half and half and stir. Taste and add salt. If you have it, add chopped flat leaf parsley and grated parmesan or romano cheese.
