3. Heat the avocado oil in a skillet over medium-high heat and sear the chicken for 6-7 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.

6. Slice the cooked chicken into thin strips.
7. Assemble the bowl by placing the cooked quinoa at the base, topping with the steamed vegetables and sliced chicken.
