Pre Heat the oven at 400F
Season the meat with salt & pepper.
Heat the oil in a large sauté pan on medium high heat.
When hot, add the meat & sear for 2 or more minutes until the meat no longer sticks to the pan and you have a nice brown color. Flip the steak, and brown that side as well.
You can then reduce the heat of the pan & continue to cook, flipping occasionally, until reaching the desired doneness,
OR place in the pre heated oven for 5-7min depending on the size.
Rest at least 4-5 minutes before serving.
