Pizza Sliders

Preheat grill to medium-high.

Mix beef, parsley, oregano, pepper and salt in a large bowl until well combined. Divide the meat into 8 equal portions and shape each into a 1-inch thick patty. Try to make all the patties the same thickness for even cooking, and shape them a little larger than the buns--they'll shrink as they cook.

Grill the patties, turning once halfway, until an instant-read thermometer inserted in the thickest part registers 130 degrees F, 2 to 4 minutes per side (for medium-rare when done; see Tip).

Spoon marinara onto each patty and top with mozzarella. Grill until the cheese is melted, about 2 minutes more. Serve the patties with lettuce on rolls.
