Heat the oil in large Dutch oven or flameproof casserole dish over medium heat until shimmering. Add onion, diced jalapeño, poblano peppers, tomatillos, salt and pepper, stirring frequently, until softened, about 5 minutes. Add garlic, cumin and oregano, and cook, stirring constantly until fragrant, about 1 minute.
Season chicken with salt and pepper, then add to the pan. Pour in the chicken stock and raise the heat to maintain a gentle simmer (avoid bringing to a boil). Cook until the chicken is cooked through, about 10 to 15 minutes. If the chicken pieces are not completely submerged, then turn them over halfway.
