2 pounds
boneless, skinless chicken breasts, pounded thin and cut into 1-inch strips
4 tablespoons
vegetable oil
1
green bell pepper, thinly sliced
1
red bell pepper, thinly sliced
1
yellow bell pepper, thinly sliced
12 (6-inch)
corn or flour tortillas, warmed (optional)
For serving (optional)
Lime wedges
Fresh cilantro leaves
Avocado, sliced
Queso fresco or cotija cheese, crumbled
Method
In a medium bowl, mix together the pineapple, lime zest, lime juice, garlic, vinegar, chili powder, cumin, salt, jalapeño, Worcestershire, cilantro, and ¼ of the sliced onion. Add the chicken and turn to coat. Marinate the chicken for 30 minutes at room temperature or up to 4 hours covered in the refrigerator.
Heat 2 tablespoons of the oil in a large cast-iron skillet over medium-high heat. Once the oil is glistening, working in batches, add the chicken in a single layer and cook, stirring occasionally, until cooked through, 15 minutes. Transfer the chicken to a plate.
Add the remaining 2 tablespoons of oil to the pan and increase the heat to high. Once the oil is smoking, add the bell peppers and remaining onion until browned and tender, 5 minutes. Return the chicken to the skillet and toss to combine.
Serve the fajita filling in the tortillas with lime wedges, cilantro, avocado, and queso fresco if desired.
