Place patties on grid over medium, ash-covered coals. Grill, covered, 13 to 15 minutes (over medium heat on preheated gas grill, covered, 13 to 14 minutes), turning occasionally, until instant-read thermometer inserted horizontally into center registers (160°F).
Season with salt as desired
Meanwhile combine salsa ingredients in medium bowl, mixing lightly. Serve burgers with salsa.
