Barbecue Pork Burger
1 1/2 pounds ground pork
1 slice red onion, minced, plus slices for serving
3/4 cup store-bought or homemade barbecue sauce
Coarse salt and ground pepper
Vegetable oil, for grates
4 soft onion rolls, split horizontally
Heat grill to medium-high. In a medium bowl, place pork, minced onion, 1/4 cup barbecue sauce, 1 teaspoon coarse salt, and 1/4 teaspoon pepper. Mix very gently with a fork to combine, being careful not to overwork meat (which would make burgers dense).
Gently form meat into 4 equal-size patties, 4 inches in diameter and 1 inch thick. With thumb, make a 1/2-inch-deep indentation in the center of each (this helps keep burgers flat during grilling).
Moisten a folded paper towel with oil; grasp with tongs and rub over grates. Season burgers with salt and pepper; grill until cooked throughout, 5 to 8 minutes per side.
Serve on onion rolls (toasted on grill, if you like), with sliced onion and remaining barbecue sauce.
