Marinate the tenderloins for 1 to 8 hours in the refrigerator.
Remove from the marinade and dry with paper towels. Rest at room temperature while you pre-heat the grill.
Preheat the grill with two zones. One side high heat (500 to 600°F). The other side cooler (around 350°F).
Sear over direct heat for around 2 to 3 minutes per side until browned. Any longer and you risk overcooking.
Move to the cooler side and cook with the lid open until the internal temperature reaches between 120°F and 125°F. Go higher if you like your tenderloins on the well-done side.
Remove from the grill and rest for 10 minutes uncovered. Slice to a thicken between ½ and ½ inch. Season with flaky sea salt and a drizzle of olive oil.
