Soup Bowl Favorite

Many years ago, my dad found this recipe in a magazine and suggested my mom try it. She did, and we all loved it.

1 small chopped onion
1 cup shredded cabbage
1 cup thinly sliced potatoes
1 cup thinly sliced carrots
1 cup diced celery
1/2 cup dry, broken noodles
1 can Cream of Mushroom soup
2 cups milk
2 Tbsp. butter or margarine
Cook vegetables in water for about 15 minutes. Add noodles and more water if necessary. Cook slowly until done. Add butter, salt, and pepper. When ready to serve, add mushroom soup and milk. Heat until hot.
