Baked Potato Soup

I found this recipe here.

¼ c. butter
¼ c. chopped onion
¼ c. flour
14 oz can chicken broth
1 can evaporated milk
2 large or 3 med. Baked potatoes
Salt and pepper to taste
Bacon (optional)
Grated cheese (optional)
Green onion (optional)

Melt butter in medium saucepan. Add onion and sauté until tender. Stir in flour, and then add broth and milk. Scoop pulp from one potato and mash; add to soup. Bring to boil and then add the rest of the potatoes (scoop the pulp and cut into cubes). Top with crumbled bacon, cheese, and green onion.
