2 pounds lean ground beef (7% fat or less)
4 ounce can sliced button mushrooms
6 ounces blue cheese
1 egg
1/2 cup seasoned bread crumbs
1 teaspoon garlic salt
2 tablespoons Worcestershire sauce
1/2 teaspoon ground pepper
1/4 cup chopped parsley

In a large bowl mix all ingredients except the mushrooms and cheese.  Divide the mixture into twelve equal balls.  Crumble the cheese into a bowl and drain the mushrooms.  Now flatten two of the meat balls into two thin patties.  Place a portion of the cheese and mushrooms onto the center of one patty and cover it with the second patty.  Without forming an air pocket, seal the edges tightly and reform the entire patty as you would a hamburger.  Pierce in about four spots with a steak knife.  Repeat this for the remaining patties until you have six hamburgers.  Chill for about one hour.  Cook on a grill as you would any hamburger adding about 10% to your usual cooking time and serve with your favorite burger garnishes.

    This is an excellent twist to an old family favorite.  Add your own touch by replacing the blue cheese with your favorite or, replace the beef with ground turkey for those avoiding red meat.
