How to Make It
In a large skillet, heat the olive oil. In a medium bowl, toss the chicken with the chile powder, cumin and salt. Add the chicken to the skillet in a single layer and cook over high heat, turning occasionally, until nicely browned on all sides and cooked through, about 8 minutes total.
On a microwave-safe plate, microwave the tortillas at high power for 30 seconds, until soft and pliable. Serve the chicken with the tortillas, lime wedges, cilantro leaves and sour cream.
