2 bell peppers, seeds and ribs removed, thinly sliced
1 large yellow onion, thinly sliced
Corn tortillas, warmed
Lime wedges for serving
Instructions
In a large bowl, whisk together the lime juice, chili powder, crushed red pepper flakes, 1/4 cup of oil, and 1 tsp. of ground cumin.
Season the chicken breasts with kosher salt and freshly ground black pepper, and place them into the marinade. Cover and refrigerate for at least 30 minutes and up to 2 hours.
Heat the remaining 1 Tbsp. of oil in a large skillet over medium heat. Add the marinated chicken and cook until golden brown and an instant-read thermometer registers 160°F in the thickest part (about 8 minutes per side).
Transfer the chicken to a cutting board and let it rest for 10 minutes before slicing it into strips.
In the same skillet, combine the sliced bell peppers and onions, adding the remaining 1 tsp. of cumin, salt, and pepper. Cook, stirring occasionally, until the vegetables soften (around 7 minutes).
Return the chicken strips to the skillet and toss with the peppers and onions until heated through.
Serve with warmed corn tortillas and a squeeze of lime juice.
Notes
Allow chicken to marinate for at least 30 minutes for best flavor. Customize with favorite toppings.
