(different) Cheese Fondue

(when I say different, I just mean not the classic cheese fondue, hehehe)

2 tablespoons butter
2 teaspoons flour
1 cup milk
1/2 cup hidden valley ranch dressing
1 cup shredded cheddar cheese
paprika (optional)
sliced green onions (optional)

Melt butter in saucepan over medium heat. Sprinkle flour in melted butter and stir constantly for 2 minutes. Whisk milk into flour mixture and constantly stir until mixture thickens and begins to boil. Lower heat to simmer; stir in cheese and ranch until smooth. Pour into a fondue pot and sprinkle in paprika and/or green onion, if desired.
