Place the black beans in a rectangle 9x12" casserole dish that has been sprayed with cooking spray or vegetable oil and sprinkle with 1/2 teaspoon of the Adobo Seasoning.
Layer the chicken breasts on top of the black beans and season with remaining Adobo seasoning. Baste the chicken with the yellow mustard.
Add 2 slices of ham on top of each chicken breast, then half a cup of the carnitas.
Bake uncovered for 30 minutes, depending on the thickness of your chicken breasts. (See Note 1)
Remove from oven and add 2 dill pickles and then 2 Swiss cheese slices to each piece of chicken. Put it back in the oven, uncovered for 5 minutes. Allow to rest 5 minutes before slicing or serving.
If chicken breasts are too thick (1 inch or more), slice in half horizontally and pound between sheets of plastic wrap for even thickness. For best results, use an instant read thermometer, the chicken is cooked when it reaches internal temperature of 165°F.
