Notes

The nutritional information provided is per serving based on dividing this casserole into 9 equal-sized servings. 
You can also boil on the stove in water or chicken broth. for approx 20-25 minutes or cut the breasts in half to reduce the time to 10-15 on medium/low heat until they are done. You'll find detailed directions in this post for how to boil chicken breasts.
*If you have time on your hands, I suggest making your own homemade shredded chicken! I like to add boneless chicken thighs or breasts to my crockpot to boil for a few hours. Check out exactly how I like to make shredded chicken using my slow cooker.
*If you DON'T have much time on your hands, pick up a rotisserie chicken from the store and remove the legs, thighs, and breast. Take out the bones and shred using two forks. You can also use a knife to chop up the chicken if it's too tough to shred properly.
