To a large bowl add the steak, oil, peppers, onion, seasoning, and lime juice. Stir to coat.
Place the mixture on the sheet pan and spread out evenly.
Broil for 8 minutes, then remove from the oven and toss everything around. Place back in the oven for an additional 8 minutes, or until the steak is cooked to your liking.
Serve alongside warm tortillas and top with your favorite fajita toppings. Enjoy!
