Saute vegetables and herbs in a small amount of oil until vegetables are soft and fragrant. Add remaining ingredients except the reserved cheddar cheese. Heat until cheese melts. Stir in cooked macaroni. Pour into an oven proof dish. Sprinkle reserved cheese on top. Bake 350 degrees 30 - 45 minutes until hot and bubbly.
This dish can be made in advanced and refrigerated before baking.
Cream of celery soup may be used instead of mushroom soup.
