Preheat oven to 350º. Clean mushrooms. remove stems( and finely chop them), place caps in 9×13 casserole dish.

in a bowl combine sausage, Worcester sauce, and finely chopped mushroom stems. mix well.

fill caps with mixture. pour melted butter over the top and bake for 45 min.

always make a double batch because even the ones who don't like mushrooms eat the filling. plus all the men in the family fight over them otherwise.:-D
