In a bowl, add avocado oil, balsamic vinegar, soy sauce, honey, Worcestershire sauce, mustard powder, garlic powder, salt, black pepper, and Italian seasoning. Mix well and set aside.

Pat the steaks dry using a kitchen towel. Place these in a plastic zip-lock bag, and pour in the marinade.

Seal the Ziploc bag and massage the steaks so that the marinade coats every inch.

Place the Ziploc bag in the refrigerator for about 20 to 30 minutes.

Place a cast pan over medium heat.

Once it is heated, place the steaks using a pair of tongs.

Press it gently to sear for about 30 seconds.

Flip the steak and press to sear it on the other side for 30 seconds.

Place the cast iron pan in a preheated oven at 350-degree F for 3 minutes.

Flip the steak so that it cooks from the other side for 3 more minutes.

Check the internal temperature of the steak. When it reaches your desired temperature, take the pan out of the oven and transfer the steak to a serving plate.

Spoon the juices in the pan over the steak and let it sit for 3-5 minutes.

Serve alongside a baked potato with sour cream, grilled red pepper, or salad.
