Optional Step but highly recommended: Season your chicken with salt, pepper, oregano, Elote spice (Trader Joes), Paprika. Add 1 tablespoons of Salted Butter and 1 tablespoons of Olive Oil to a pan and sear your chicken on both sides. DO NOT cook through, just to a nice golden brown for color.
In the bowl of your crockpot, combine the onion, chicken, hot sauce, garlic powder, paprika, chipotle chili powder, diced tomatoes, poblano peppers, jalapeƱos and celery. Stir in 2 cups broth. Add the butter slices. Season with salt and pepper.
Cover and cook on low for 5-6 hours or high for 3-4 hours.
Shred the chicken using two forks. Stir in the cream cheese/yogurt, and cilantro.
