BBQ Pork Burgers

1 1/2 pounds ground pork
1 small red onion, minced
3/4 cup bbq sauce
salt and pepper
vegetable oil for grates
4 soft onion rolls

Heat grill to medium high. In a medium bowl, place pork, minced onion, bbq sauce, salt, pepper. Mix gently with a fork to combine, dont overwork the meat or your burgers will be too dense.
Gently form meat into 4 equal size patties, 4 inch in diameter and 1 inch thick. With thumb, make an 1/2 inch deep indentation in the center of each ( this helps the burgers stay flat during grilling).
Moisten a folded paper towl 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 is best) with sliced onion and remaining bbq sauce.
