This started out as a crock pot "experiment" and it turned into a delicious "accident!" Good thing I wrote down what I did or I probably wouldn't be able to duplicate it again! YUM!! So filling! Half a burrito is more than enough to satisfy!
Place chicken (does not need to be thawed), cream cheese, beans, corn, tomatoes, taco sauce, and chilies in slow cooker; cover and cook on low for 6 hours. Stir every 2 hours or so.
Remove chicken pieces from crockpot and set aside on cutting board. It's ok if some of the beans, etc is mixed in.(Leave heat on low in crockpot.) Shred chicken. Salt and pepper to taste.
Whisk flour into sauce in hot crockpot until well combined and mixture thickens. Cover and turn off crock.
Preheat oven to 350 degrees F. Lightly spray a 13x9 casserole dish with nonstick spray.
Cook rice per package directions. Add to shredded chicken mixture; stir to combine.
Fill the 5 extra large tortillas with chicken mixture; fold burrito style and place in prepared casserole pan. Ladle thickened sauce from crock over the burritos in dish. Cover entire dish with shredded cheese of choice.
Bake in preheated oven for 22 minutes. Turn broiler on and broil for 3 minutes until cheese is bubbly and lightly browned. Remove from oven and serve with lettuce, sour cream, avocado and any other toppings of your choice.
