Cheesy Meat Loaf

1 1/2 pounds ground beef

1 egg -- slightly beaten

1 tablespoon Worcestershire sauce

1/4 teaspoon salt

1/4 teaspoon pepper

1/2 cup milk

1/4 cup onion -- chopped

1/3 cup dry bread crumbs

1 cup cheddar cheese -- grated

4 ounces canned mushrooms pieces -- drained

TOPPING: 5 tablespoons brown sugar

1 teaspoon dry mustard

1/2 cup catsup

Combine beef, egg, Worcestershire sauce, salt, pepper, milk, onion and bread crumbs. Mix well. Roll out on waxed paper into a rectangular shape about 1/2" thick. Sprinkle cheese and mushrooms on top of beef mixture. Roll lengthwise like a jelly roll by picking up edge of wax paper and allowing meat to roll over on itself. Bake at 350 for 10-15 minutes, then add blend of brown sugar, mustard and catsup. Finish baking until topping bubbles, about 30 minutes.
