Place the steak(s) on a rimmed baking sheet, lightly oil both sides then season with salt and garlic. Set aside while oven preheats to 250 degrees F.
Bake the steak(s) for approximately 30-45 minutes until the internal temperature reaches your preference, (145 F medium-rare to 165 F medium-well).
Remove from the oven and allow a few minutes for the steak to rest, meanwhile heat a skillet or grill VERY hot.
Sear or grill the steaks on both sides.
Remove steak from skillet or grill and cut against the grain on a slight diagonal bias for the most tender and juicy steak strips.
For the sauce:
While the steak is in the oven, combine all sauce ingredients in the work bowl of food processor and pulse until everything is finely minced and combined or puree all the way until smooth if you prefer a smoother texture.
Spoon over grilled steak, chicken or fish and grilled vegetables.
