Remove the steak from the refrigerator and let it come to room temperature for about 30 minutes.
Season both sides of the steak with salt, black pepper, and garlic powder (if using).
Heat a grill pan or skillet over high heat and add 15 ml of olive oil.
When the pan is hot, add the seasoned steak.
Cook the steak for about 3-4 minutes on each side for medium-rare, or adjust the cooking time to your desired level of doneness.
Remove the steak from the pan and let it rest for a few minutes before slicing it thinly against the grain.
