Baked Scallops with Garlic Sauce recipe

1 1/2 pounds bay scallops, cut in halves
3 cloves garlic, mashed
1/4 cup (1/2 stick) margarine, melted
10 firm white mushrooms, sliced
Light dash of onion salt
Dash of freshly grated pepper
1/3 cup seasoned bread crumbs
1 teaspoon finely minced fresh parsley

Wipe scallops with damp paper towel. Mash garlic cloves and add to margarine; stir well to blend. Keep warm. Pour a little of the melted garlic sauce into the bottom of a baking dish; add the mushrooms and season. Place the scallops on top of the mushrooms. Reserve 1 tablespoon garlic sauce and drizzle the rest on scallops. Sprinkle with bread crumbs, parsley and reserved garlic sauce. Bake in preheated 375 degrees F oven until the top is nicely browned and bubbly hot.
