Preheat your oven to 350 degrees and spray a casserole dish or cast iron with cooking spray.
Next mix all your ingredients (shredded chicken - pepper jack cheese) together in a large bowl and pour it into your prepared dish.
Sprinkle extra pepper jack cheese (and/or cheddar cheese) on top and bake the dip for 25-30 minutes or until the cheese has melted and the dip is hot all the way through.
Top with your granishes and serve immediately with your favorite tortilla chips!
