Heat oil in a large Dutch oven over medium-high heat. Season chicken with salt and ancho chile powder. Sear, skin-side down, in the oil until golden brown. Turn over and brown on the other side. Remove the chicken to a plate.
Add the onion to the pan and cook until lightly golden brown. Add the garlic and cook for 1 minute longer. Add the chicken back to the pot, add the chiles, stock, and cilantro, and bring to a boil. Cover and roast in the oven until the chicken easily falls away from the bone, about 40 minutes. Remove the chicken from the pot and strain the cooking liquid into a bowl.
When the chicken is cool enough to handle, remove bones and cut or shred the meat into bite-sized pieces. Place the reserved cooking liquid into a medium saucepan and bring to a simmer. Add the shredded chicken, turn off the heat and let warm.
Divide the warm chicken among the warm tortillas, top with Salsa Verde and chopped cilantro.
Heat oil in a large skillet over medium heat. Add the onions and jalapeno and cook until soft. Add the tomatillos and cook until soft, about 10 to 15 minutes. Transfer the mixture to a blender, add the lime juice, honey, and cilantro, and blend until smooth. Season with salt and pepper.
