Heat 1 tbsp. olive oil over medium-high heat in a large skillet and let that get hot. Season the chicken with 1 1/2 tsp. salt and 1 1/2 tsp. pepper and place into the hot oil. Cook about 4-6 minutes per side, or until well-browned and cooked through.
Once the chicken’s cooked, remove from the pan, set on a cutting board, and dice into small, bite-size pieces. Then, return to the same pan.
For clean diets, you can use chicken breast instead of chicken thighs and choose high quality, refined grain-free corn tortillas.
