First, prep all of the ingredients for the recipe. In the crockpot, add the chicken, beans, enchilada sauce, can of Rotel and the diced onion.
Cook on high for 4 hours or low for 6 hours. Remove the chicken, then chop and shred it.
Place the chicken back into the crockpot and mix with other ingredients.
Top with shredded cheese then cover and allow the cheese to melt. This will not take more than 15-20 minutes.
Before serving add in the crushed corn chips across the top of the casserole then serve.
For some fresh ingredients garnish with fresh, diced tomato and cilantro.
