Notes
This recipe makes a large batch of chicken. Use extra chicken to fill burritos, top salads or make entree style tacos throughout the week.
When assembling the taco bites, chicken can be cold and pulled straight from the fridge. It will reheat in the oven while the shells are baking. Top as directed.
