Coat the roast with a thin layer of dijon mustard.
Season with sea salt, pepper, thyme, garlic, and fresh chopped cilantro. Press seasonings into meat.
Heat olive oil to high in a pan (I love cast iron). For a rare done-ness, sear for 6 minutes turning to get all sides.
*Bake in oven at 375 for a few extra minutes to get med-rare finish.*
Remove from pan, cover in tin foil, and let it rest for 5 minutes
