Heat a large pot on medium and add the extra virgin olive oil. Then add the pork cubes and cook for about five (5) minutes, stirring regularly. You want the cubes to just start to brown.
Add the onions, carrots, celery, garlic, and salt. Cook until soft and translucent, 5-10 minutes.
Add the potatoes, green chile, and any other desired vegetables to the pot. Stir to combine and cook for another ten (10) minutes.
Add the chickpeas, soy sauce, cumin, oregano, garlic powder, onion powder, mustard seed, and flour. Stir to combine. Cook for one (1) minute.
Add the broth. Cover and cook on a low simmer for 30-40 minutes.
Serve with a warm tortilla. The stew's great plain, but it's also great with cheese, sour cream, lime juice, and cilantro.
