Step 1Tear one hamburger bun into pieces. Place in food processor or blender container. Cover; pulse on and off, to form fine crumbs.
Step 2Combine Ground Beef, 1/2 cup bread crumbs, onion, egg white, garlic, salt and pepper in medium bowl, mixing lightly but thoroughly. Lightly shape into eight 1/2-inch thick mini patties.
Step 3Place patties on grid over medium, ash-covered coals. Grill, covered, 8 to 9 minutes (over medium heat on preheated gas grill, 9 to 10 minutes) until instant-read thermometer inserted horizontally into center registers 160°F, turning occasionally. About 1-1/2 minutes before burgers are done, place rolls, cut sides down, on grid. Grill until lightly toasted.
Cooking Tip: To broil burgers, preheat broiler. Place burgers on rack in broiler pan so surface of beef is 2 to 3 inches from heat element. Broil 9 to 10 minutes to medium (160°F) doneness, turning the burgers once. Place buns, cut sides up, on broiler pan so surface is 2 to 3 inches from heat element. Broil 45 to 60 seconds or until lightly toasted.
Step 4Serve burgers in buns with Topping Variation(s), as desired. Close sandwiches.
