Sprinkle both sides of steaks with salt and pepper and coat with a thin layer of arrowroot powder.

Drizzle olive oil in a large skillet over medium heat and cook for 3 minutes on each side or until browned. Remove steak from pan and set aside.

Add mushrooms, vinegar, broth, and lemon juice to the pan and simmer for 10 minutes or until mixture is reduced. Add arrowroot + water mixture and whisk into the pan until you reach your desired consistency. Return the steak to the pan. Cover and cook for an additional 2 minutes until steak is cooked to your liking.
