Grill: Heat the grill to medium high. Season the steak with salt, at minimum, or anything else that floats your boat. Sear each side for a minute or two. We're looking for Maillard reaction - that's brown and crispy. Move steaks to a lower heat and cook for another couple maybe 4-5 minutes. Take off the heat and let rest for 5 minutes, if you can wait.
Oven: Heat oven to 425 F. Heat a cast-iron skillet over high heat on stove, and add a pat of butter or oil. Season the steak as your heart desires. Same idea as above: sear each side for a minute or two until browned and then transfer skillet to the oven for a few minutes, maybe 4 or 5. Take out and let rest for 5 minutes. We dare you.
