To make the marinade, combine the soy sauce, lime juice, and Mexican seasoning (see separate recipe) together in a bowl. Add the steak, cover, and leave to marinate for at least an hour.

Place a grill pan over a medium heat and add the peppers. After 5 minutes, add the steak, and cook until done to your liking. Discard any remaining marinade.

Let the steak rest for 5 minutes, and continue to cook the peppers if necessary. Meanwhile, place the tortillas onto a serving plate, and then divide the peppers between them. 

Next, slice the steak and divide it between the tortillas. Carefully tear apart the burrata and roughly divide it between the tortillas. 

To finish, garnish with cilantro, lime wedges, jalapeños, and black pepper.
