Sandwiches for a Crowd Recipe

Cut the bread in half lengthwise. Hollow out top and bottom of loaves, leaving a 1/2 inch shell (discard removed bread or save for another use). Combine cheeses, onions, salad dressing (or mayonnaise) and Worcestershire sauce; spread over cut sides of bread. Layer ham and roast beef on bottom and top halves; place pickles on bottom halves. Gently press halves together. Wrap in plastic wrap and refrigerate for at least 2 hours. Cut into 1 1/2 inch slices. Yield 12-14 servings.
