This style of taco is called tacos de alambre, and it’s basically meats, onion, and peppers cooked in a skillet, topped with cheese, then everyone gets stuck in with tortillas.
Freeze the steak for 30 minutes or until you're able to slice super thinly.
Sauté the peppers and onions until soft, along with the pickled chillies and taco seasoning.
Remove from the pan and set aside. Add the steak along with a splash of oil in a skillet over high heat.
Sear the sliced steak, then add in some more taco seasoning and the peppers back in. Finish with a squeeze of lime
Top with slices of provolone, then pop under the grill or into the oven to melt.
Finish with lime wedges and fresh coriander, and get stuck in!
