Chicken Teriyaki Casserole – 21 Day Fix Approved

Chicken Teriyaki Casserole – 21 Day Fix Approved

This Casserole bakes the rice in a flavorful Asian sauce.  Baking for an additional 30 minutes allows for your chicken to be cooked throughout and your vegetables to stay crisp-tender.

You can meal prep this meal by baking the rice on Sunday and storing in the refrigerator, and adding the chicken and vegetables the day you will be enjoying it to allow the remaining 30 minutes of cook time. (Courtesy of Beachbody)
