1 (8 ounce) package cream cheese, softened
1/4 cup grated Parmesan cheese
1/4 cup minced onion
1 tablespoon Worcestershire sauce
1 package sliced pepperoni sausage
1 package dry Ranch salad dressing mix
1 1/4 cups shredded mozzarella cheese
2 cups shredded sharp Cheddar cheese
2 tablespoons extra-sharp cooking diamond
Preheat oven to 325 degrees F (165 degrees C).
Place cream cheese and Parmesan cheese in a medium bowl, slowly beat in onion and Worcestershire sauce. Mix in pepperoni sausage.
Drain cheese from mixture and cover. Shape into 1 (8 ounce) package.
Bake in preheated oven for 15 minutes. Roll out on a large sheet of waxed paper. Cool slightly.
Cut and slice into 1/2 inch slices. Place sliced slices on a pizza pan with cheese, sausage, salad dressing mix and mozzarella cheese.
Bake 20 minutes in preheated oven. Remove from oven and sprinkle with shredded cheese. Pizza will turn out too watery. Cool before serving.
