I'm a medium saucepan, I cooked and stirred 1 1/2 cups of small broccoli flowerets, 1 cup of sliced mushrooms, 1/2 cup of carrot, 1/4 cup of chopped onion in 1/4 cup of hot margarine for 7 minutes, until the vegetables were tender. My partner stirred in 1/4 cup of all purpose flour, 1/2 teasooon of dried, crushed basil, and 1/4 teaspoon of pepper. Then, I added 3 cups of milk and 1 cup of half-and-half, which could be substituted with light cream, all at once. My partner added 1 tbsp of Worcestershire sauce and 1 1/2 teaspoons of instant chicken bouillon granules. I cooked and stirred it until it was thickened or bubbly. After that, my partner stirred in 1 1/2 cups of chopped, cooked chicken and heated it through.
