One of our holiday traditions is to make a bunch of appetizers on Christmas Eve and munch away. My mother-in-law always made Party Pizzas and they are a favorite.
They are very simple. Spread cocktail bread (we like pumpernickel) with tomato paste. Sprinkle on some ground oregano. Top with browned Italian sausage and shredded mozzarella cheese. Bake on a cookie sheet at 400 degrees until the cheese melts and browns a little. Yum!
