Bring your steak to room temperature 30 minutes before cooking.
Make sure to dry it well and season heavily with salt.
In a well heated pan, add vegetable oil and then add the steak.
Leave it on the first side for 6 minutes. Then flip on the other side.
Once you flipped, add the butter and rosemary and start basting your steak.
Leave it on the second side for 5 minutes and take it out.
Cut your steak and top it with the butter sauce.
Top with some teriyaki sauce and sesame seeds. Serve along with potato wedges or any side you'd like!
