Preheat outdoor grill or stovetop grill pan to medium heat. In a large bowl, mix together the ground beef, salt, pepper, garlic, and Worcestershire sauce. Shape into 12 even 2-inch-wide patties and place on a plate or tray.
Brush each side with oil, and place patties on the hot grill. Cook for about 4 minutes, turn over, and continue to cook for another 4 to 6 minutes, for medium rare, or 2 to 4 minutes longer if you want them well done.
Place 2 pieces of cheese on each, along with 2 half pieces of bacon, and cook for a minute or two, so that the cheese melts. Close the grill or turn off the heat and transfer the sliders to a platter or tray.
To assemble the sliders, slice the King’s Hawaiian rolls in half horizontally and spread each half with Heinz Mayochup. Place a bacon cheese slider on each bottom half, and top with one crispy onion ring, and a piece of lettuce. Replace the top half of the buns, and skewer with a long toothpick. Serve immediately.
