Preheat your Traeger or other pellet smoker to 350F
Prepare the shredded chicken if it is not already shredded.
In a medium bowl, combine shredded chicken, room temperature cream cheese, 1 ½ cups shredded cheese, taco seasoning, green chiles, and a 1 cup of canned enchilada sauce.
Mix the ingredients together until they are well combined and transfer into your cast iron pan or baking dish. Add the last ½ cup of shredded cheese to the top of the dip.
Set the prepared dip directly on the Traeger grill grate and close the lid. Cook the dip for 30 minutes or until the cheese is totally melted and bubbly.
