Meanwhile mix water or chicken broth with mole sauce in large skillet and heat, stirring to dissolve mole. When mixture comes to a soft boil add the chicken and simmer. Adjust seasoning, as needed with additional salt.

Sprinkle 1 to 1 1/2 cups of shredded pepper jack cheese on top of chips. Spoon the Chicken Mole on top of cheese and place into the oven. Heat in oven until cheese melts.
