Place the steak in the freezer for 20–30 minutes to firm up, then thinly slice. Place the sliced steak and dry seasoning in a bowl and mix to combine.
In a pan over high heat, add a light coat of spray oil and the steak. Sear for 2 minutes, or until golden. Remove and repeat in batches to avoid overcrowding the pan and stewing the meat.
In the same pan over medium-high heat, add a touch more spray oil, the onion, bell pepper, and a pinch of salt and pepper. Sauté for 5–6 minutes, mixing regularly.
Add the seared steak, any resting juices, and the Worcestershire sauce. Mix to combine and adjust the seasoning. Add half of the mozzarella and mix until melted. Remove from the heat.
Slightly warm the tortillas to make them easier to fold. Add the remaining mozzarella to each tortilla, 20g (0.7oz) each. Top with ⅕ of the cheesesteak mix and drizzle with sriracha sauce (or sriracha mayonnaise, or any sauce of choice — confirm which you used). Wrap and fold tightly.
Toast in a dry pan over medium heat, or place on a baking tray, lightly spray with oil, and bake at 200°C (390°F) for 8–10 minutes, until golden and crispy. To air fry, lightly spray the wraps and cook at 200°C (390°F) for 5–6 minutes, until golden and crispy, in batches.
