Hamburger Steak Sliders
In a large bowl, combine onion, broth, parsley (if using), steak sauce, mustard and pepper. Add ground sirloin and chuck; lightly mix together until just combined (do not overmix). Divide meat mixture into 12 portions and shape into 1/2-inch-thick patties.Advertisement
Place patties on the greased rack of a gas or charcoal grill directly over medium heat. Cover and grill for 8 to 10 minutes or until done (160°), turning once. Wrap buns in heavy foil and add to grill rack the last 5 minutes of grilling, turning once.
Or preheat broiler. Place meat patties on the rack of a broiler pan. Broil 3- to 4-inches from the heat for 8 to 10 minutes or until done (160 degrees F), turning once halfway through broiling.
