salt and peppa, high heat.
I like to put some cast iron in the oven at 500 or 550. Let it sit for 5 or 10 minutes like that. Take it out, put the steak in, put in the oven.
Wait about 2 or 3 minutes, flip
Wait 3 or 4 minutes
take it out, put a pat or two of butter on it
let it sit a minute
eat
or grill it, similarly but you need that grill to be HOT
