1. Sprinkle the pork with flour to lightly coat.
2. In a large pot (I use a Dutch oven), brown the meat in oil.
3. Add chiles, chicken stock, vegetables, salt& pepper, and water if needed.
4. Bring to a boil, lower heat to medium low.
5. Cover and simmer until meat and vegetables are done, and the stew is slightly thickened (about 3 hours).
6. You may cook in a crockpot for 6-8 hours.
7. Serve with flour tortillas.
