Sometimes simple is best.
1 1/2 pound sirloin steak
1 tablespoon olive oil
Kosher salt and freshly ground black pepper
Set your grill up for a directed cook over medium-high heat (450-500°F).
Brush steak with oil and salt and pepper to taste.
For medium rare, grill for 4 to 6 minutes on each side, or until the meat reaches 130°F internal. Remove from grill and let it rest about 5 minutes, then cut crosswise into thin slices.
We served it with sauteed green beans and this excellent roasted beet salad.
