Pepper Cream Gravy

I forgot to add the chives before the picture, and I just ate the rest of the gravy, so it's too late for another picture. Sorry.

1 tablespoon butter or stick margarine
2 tablespoons all-purpose flour
1 cup 1% low-fat milk
1/2 teaspoon freshly ground black pepper
1/4 teaspoon salt
2 tablespoons chopped fresh chives

Melt 1 tablespoon butter in a saucepan over medium heat. Add flour, and cook for 1 minute, stirring constantly. Gradually add 1 cup milk, 1/2 teaspoon pepper, and 1/4 teaspoon salt; stir with a whisk. Bring to a boil; stir constantly. Reduce heat, and cook 5 minutes, stirring occasionally. Serve gravy on mashed potatoes wtih garlic; sprinkle with chives.
