Sauté onions, celery and peppers until onions are transparent.
Add all of the ingredients (except the noodles and parmesan) and heat over medium until the cheddar melts.
Add the noodles, mix well, and turn into a greased 2 quart casserole dish. Sprinkle the top with parmesan cheese and an equal amount of dried bread crumbs, if you would like. Bake at 425 F for 20 minutes.
