Remove steaks from refrigerator and bring to room temperature. Clean each steak by rubbing lime or lemon, rinse with cold water and pat dry. (this step is optional if you are not use to cleaning steak). Season each steak with salt and pepper. On a hot griddle pan, pour oil, place steaks gently and let cook 6 to 8 minutes on each side depending on the thickness of the steak. If using indoor or outdoor grill, spray grill with cooking spray before grilling steaks.
While the steaks are grilling, prepare the vinaigrette. In a small bowl, add juice of lemon or lime, olive oil, scallions, garlic, hot pepper, salt and freshly ground black pepper.
Remove steaks from pan, place on a plate to rest for a few minute. Serve vinaigrette on top or on the side.
