Start by preparing the pork meat and cut into cubes, reserving the bone if applicable.
Season the cubed pork generously with southwest seasoning and toss to coat.
Mince the garlic, chop the onion, jalapeno, and red bell pepper, and reserve.
Heat a heavy pot or large pan with oil and bring up to temperature over medium-high heat.
While cooking in batches (in my case, 3 or 4 batches), sear the seasoned meat and bone (bone is optional). Next, turn over the pork cubes after the cooked side is seared. Follow this by continuing to cook the opposite side of the meat. Once the meat has been browned, add the chicken stock and stir to get the fond at the bottom of the pot/pan. Top with the diced garlic, onion, jalapeno, and red bell pepper, and bring to a low boil. Reduce the heat to medium-low and cover with a tight-fitting lid. Cook for approximately 2 hours or until the pork is fork-tender.
Add the fresh chili Verde sauce, extra cilantro, and fire-roasted Hatch chilies (optional). Stir to incorporate.
