1Preheat oven to 400. Arrange bread slices in single layer on a lightly greased or nonstick baking sheet. Mix Worcestershire sauce and onion in a bowl. Baste one side of each of the bread slices with the Worcestershire sauce mixture. Top each slice with 1 tsp. of the salad dressing. Cut the pastrami slices and cheese slices into 2 inch pieces to cover the bread slices. Layer each slice with one piece of the pastry and one piece of the cheese. Bake for 5 minutes or until the cheese melts. Top with the sprouts if desired. Makes 2 dozen bites.
