1 beaten egg
1/3 cup fine dry breadcrumbs
1 tsp prepared mustard
1/8 tsp pepper
dash of garlic powder
1 1/2 lbs lean ground beef
3/4 cup crumbled blue cheese
6 hamburger buns, split
olive oil
In a medium bowl combine the egg and Worcestershire sauce. Stir in the breadcrumbs, mustard, pepper, and garlic powder. Add the ground beef and mix well. Divide the mixture into 12 patties about 1/4-inch thick. Place about 2 tablespoons of the blue cheese atop 6 of the patties. Spread to within 1/2-inch of edges. Top with remaining patties. Press meat around edges to seal well.
Place patties on a grill of medium-hot coals and grill for about 14-15 minutes, turning once during cooking.
To prepare buns, brush insides with olive oil. Place on grill to heat until toasted. Serve patties on buns with your choice of condiments.
