Cheap Mushroom

I had a craving for mushrooms and the mushroom lady was selling her "old" mushrooms for cheap. She gave me twice the amount I asked for at half the price. Who am I to complain? I figured I would wing it and try a cream sauce.

Mushroom Cream Sauce
1 tblsp butter
1 pint mushrooms sliced
salt and pepper
1 tblsp flour
3/4 cup whole milk
1/4 cup half & half
2 oz fontina cheese
Melt butter over medium heat. Add mushrooms and cook until tender. Salt and pepper to taste. Add flour and stir to coat mushrooms. Add milk and half and half. Heat slowly until sauce thickens. Add cheese and heat until it melts. Remove from heat.

I used my sauce in a casserole, but I think it would have been delicious over chicken. I just wasn't able to make anything right away, so casserole seemed the best option.
