In a 6-quart crockpot or slow cooker, place a liner in the crock pot or coat it with cooking spray.
Place the chicken on the bottom of the crockpot.
Top the chicken evenly with the Rotel and Black Beans.
Cover and cook on low for 8 hours.
Use 2 forks to shred up the chicken.
Place your tortilla chips on a plate or sheet pan and top with your toppings of choice. (Note - If you need to melt the cheese, you can place the tortillas on a baking sheet, top them with cheese and then bake in the oven at 350*F for 5-10 minutes, then continue with topping the nachos.)
Use a slotted spoon to remove the chicken and top the nachos with the chicken and any additional toppings.
Serve.
