In a large, deep, frying pan on medium low heat, And just a tablespoon or so of olive oil and add the cubed chicken. Cover while cooking right from the start! This does not really fry the chicken. it ends up releasing the juices and sort of boils and steams the chicken. Turn the heat down if it looks like it's frying.
Stir in the onion, fresh peppercorns, dried Entero Pepper, and any other peppers you have diced and let it cook, stirring occasionally.
Once the chicken is cooked to the center of the cubes, add the remaining ingredients and stir, there should be enough liquid to cover about half of what is cooking, if there isn't, add some water or chicken stock. Add as much rice as you like to bulk up the chili, using 1 bean can of rice is simply a guide.
Simmer until you are too hungry to wait any longer. Add hot sauce if desired.
A note on the 4 Bean Salad, I use this brand, fiamma. If using this brand I use the liquid from the can as well, just open and pour the contents into the pan. If using other brands, I normally drain that liquid and use water or chicken stock as the liquid, basically open the can, drain, add water or chicken stock to the contents of the can, then pour that into the pan, there, you have the right amount of liquid.
