Instructions
In a large bowl, combine the beef and cornstarch and toss to coat the beef evenly.
Heat 1 tablespoon of the oil in a large skillet or wok over medium-high heat. Add the beef and sear until just browned. Transfer the steak to a bowl, add the Worcestershire sauce and liquid smoke and toss to coat. Set aside.
Heat the remaining oil in the same pan over medium-high heat. Add the onion, bell pepper, and jalapeño and cook for 3 to 5 minutes, until soft. Season the vegetables with salt and black pepper. Add the steak and cook for 1 to 2 minutes to heat through.
Serve the steak and vegetables in the tortillas with optional toppings on the side.
