Mushrooms Au Gratin

8 oz mushrooms, sliced
1 tbl butter or margarine
1/4 c. light sour cream or plain Greek yogurt
1 tbl soy flour (white flour works OK)
1/2 c. shredded Cheddar cheese
2 tbl grated Parmesan cheese

Preheat the oven to 350F.

Melt the butter in a non-stick skillet. Saute the mushrooms until softened.

Spray a shallow baking dish with cooking spray. Place the mushrooms in the dish. Mix the sour cream, flour, and cheese in a bowl. Pour the sour cream mixture over the mushrooms. Sprinkle evenly with the Parmesan.

Bake 15-20 min. or until hot and bubbly.
