Six ingredients are all you need to prepare these delicious, delectable deli burgers.
Combine Ground Beef and Corned Beef, mixing lightly but thoroughly. Lightly shape into six 1/2-inch thick patties.
Place patties on grid over medium, ash-covered coals. Grill, covered, 8 to 10 minutes (over medium heat on preheated gas grill, covered, 7 to 9 minutes) until instant-read thermometer inserted horizontally into center registers 160°F, turning occasionally. Evenly top with cheese during last minute of grilling. About 4 minutes before burgers are done, place bread on grid; grill until lightly toasted, turning once.
Spread mustard over each slice of rye bread and cut in half. Place burger on one side of bread; top with pickles. Close sandwiches.
Test Kitchen Tips Make sure your grill is clean (to prevent flare-ups) and the rack is well-oiled (to prevent sticking).
