Beef & Bulgur Burgers with Blue Cheese for Two

Combine onion, vinegar, water and sugar in a small saucepan. Bring to a boil and cook for 2 minutes. Remove from heat and set aside, stirring occasionally.

Combine beef, bulgur, blue cheese, celery salt (or salt) and pepper in a medium bowl; use your hands to gently combine. Form the mixture into 2 patties, about 4 inches in diameter.

Heat oil in a medium nonstick skillet over medium heat. Cook the burgers until browned and an instant-read thermometer inserted into the thickest part registers 165 degrees F, 4 to 6 minutes per side. Drain the pickled onion. Serve the burgers on lettuce leaves, topped with onion.
