This juicy hamburger is full of flavor and topped with decadent blue cheese.
Heat a grill or grill pan until medium hot. Combine meat, parsley, Worcestershire, paprika, salt, and pepper. Shape into ten 1/2-inch-thick patties. Grill, turning once, 4 to 5 minutes per side for medium rare. Serve burgers on bread with blue cheese, tomatoes, onion, and lettuce.
