Broccoli Cheese Soup

This delicious recipe is from the school cafeteria where I work...It's GREAT in bread bowls! I've broken it down to make about 4-5 servings.

1/2 c. (1 cube) butter
1/2 c. flour
1/4 can evaporated milk (3/8 c.)
4 c. water
1 TB. chicken base or chicken bullion
1/4 tsp. salt
1/4 tsp. pepper
3/4 lb. broccoli
10 slices processed American Cheese

In saucepan over medium heat, melt butter; add flour and blend thoroughly into thin paste. Add liquid and stir well. Add spices and chicken base. Add broken up slices of cheese, stirring often. Cut up broccoli and steam lightly (since I don't have a steamer, I boil the broccoli briefly in water and drain). Add broccoli to soup base. Simmer.
