Fried potatoes via Lodge cast iron fry pan on the grill, to go with rubbed pork chops. Turned out very good. We have a cheap 5 burner gas grill and the burner tents were rotting out. So I removed them, found a grate to go over the burners and covered it with lava rock. Heat retention is WAY better, and temperature was notably hotter after the rock heated up. Seems like it is officially Science week and I'm digging it.
