As I mentioned above, you can make this recipe with chicken breasts or chicken thighs. If you substitute boneless, skinless chicken thighs just season them with salt and pepper and cook them over medium high heat for about 8-10 minutes until nice and brown. You'll remove the chicken from the skillet and proceed with the recipe. Once you add the chicken back into the sauce, you will want to continue to cook the chicken until the internal temperature of the chicken is 165 degrees F.
