Potato Soup
["2 Tbsp. butter", "1/2 c. onions, diced", "1 c. carrots, diced", "1 c. celery, diced", "4 c. potatoes, diced", "2 Tbsp. parsley", "10 1/2 oz. can condensed chicken broth", "3/4 tsp. salt", "1/8 tsp. pepper", "3 1/2 c. milk", "1/4 c. flour", "1/2 c. milk"]
["Heat butter in a 3-quart saucepan. Saut onions until tender (low heat) about 5 minutes. Add vegetables, broth, salt and pepper. Cover and simmer until the vegetables are tender but not over cooked. Reduce heat. Add the 3 1/2 cups milk. Heat the soup until the milk is hot (do not boil). Blend flour with 1/2 cup cold milk and add slowly to soup, stirring constantly. Cook very slowly until soup is bubbly and slightly thickened. Do not boil."]
