Preheat the oven to 350 degrees.

In a large bowl, mix together the chicken, rotel, cream cheese, sour cream, taco seasoning, and cream of chicken soup. Stir to combine well.

Layer a small amount of the chicken mixture in the bottom of a well-greased 9x9 baking dish.

Place a layer of crumbled Doritos on top of the chicken mixture.

Add another layer of the chicken filling.

Place another layer of crushed Doritos on top.

Add the remaining chicken mixture, and top with one more layer of crushed Doritos and the cheese.

Bake for 20-25 minutes and top with freshly chopped parsley before serving.
