To make this sandwich you will first want to begin by gathering all of your ingredients. Once you are sure you have everything, go ahead and prep each ingredient.
Begin by cooking the chicken. Do you want to be sure the internal temperature of your chicken reaches 165°F before it is considered fully cooked. Once it is cooked, remove the chicken from the burner and be allowed to call for a few minutes. Once it has slightly cooled pull the chicken into shredded pieces.
Now, we recommend using a cast iron skillet with great on it which will give you nice grill marks on your sandwich. Place the cast-iron skillet over medium-low heat and allow it to warm while you are preparing the rest of the ingredients.
Brush the bottom of the pan with oil, then add your bottom layer of bread to the pan. Assemble your sandwich by layering shredded chicken, sliced cheese, peppers, avocado, and chipotle sauce. Once assembled, add the top layer of bread. If you have it available, add a weight on top to press the sandwich as it melts.
When the sandwich is starting to melt, in the bottom is nicely browned, carefully flip the sandwich over and warm the other side. If desired, you can brush oil on the pan before setting the sandwich down on the opposite side so that you add grill marks to the top of the sandwich as well.
Allow the sandwich to melt over medium to low heat until the cheese is melted, and the sandwich is warmed. Once warmed, remove from the heat, serve, and enjoy!
