Dice avocado, onion and tomatoes. Chop cilantro and mince garlic. Mix with avocado oil until all ingredients are incorporated
Heat a cast-iron skillet on high pour in avocado oil and place your steak into the skillet and char on both sides. Lower the heat to medium and finish cooking steak to your desire.
