2) Dice the onions and yellow pepper. Heat the oil in a large Dutch oven or casserole. Add the onions, yellow pepper, poblano peppers, crushed garlic, chilli powder and ancho chilli powder. Saute this mixture until the onions are tender, 5 to 7 minutes.
3) Add the diced chicken breast and continue to cook until the chicken is fully cooked, 10 to 15 minutes depending on the size of your dice.
4) Wash and stem the tomatillos then run them through a food processor until they are pulverized, but still have some texture (you could dice them by hand, but this will leave the tomatillo skins floating around in your finished product).
5) Add the tomatillos and the stock to the chicken and pepper mixture. After this is heated through (about 10 minutes), check the spiciness and, if necessary, add either a finely chopped jalapeno or serrano pepper for more heat (we're looking for a slow, sustained burn, not fire).
6) Season, to taste, with salt and pepper. Simmer for 30 minutes to meld the flavours. Add the beans and coriander, cook a final 5 minutes to heat thoroughly and serve with a garnish of coriander leaves and a lime slice.
