Preheat a grill to high or a stovetop grill pan over high heat. In a bowl, toss the short ribs with the oil and garlic powder and season liberally with the remaining 1/2 teaspoon salt and a few grinds of pepper. Grill each slice for 2 to 3 minutes on each side, transfer to a cutting board, and let rest for 5 minutes. Cut into bite-size pieces.
