Crock Pot Cheesy Chicken & Rice

I've had this recipe pinned on pinterest for a while. It's really simple to make and if you find a good sale on chicken it can be very inexpensive too.

4 boneless skinless chicken breasts

1 large onion, chopped

1 -8 ounce box Zatarain's Yellow Rice Mix, cooked according to directions

1 cup cheddar cheese

1 can cream of chicken soup

1 can whole kernel corn, drained

Place chicken and onions in crock pot.  Pour cream of chicken soup over top. Cook on low for 7-8 hours.  Mix in rice, corn, and cheese.  Cover and cook for a few more minutes.
