Over medium heat in a Dutch oven, brown ground pork until no longer pink. Drain and set aside. Meanwhile, in a small skillet, crisp bacon. Drain and set aside, reserving 1 tbsp of the fat.
While the pork and bacon are cooking, chop the onion, celery, green and red pepper, and garlic. (Or use pre-chopped garlic.)
In the Dutch oven, heat the reserved bacon fat over medium low heat. Add onion, garlic, celery, green and red peppers. Sweat, stirring occasionally, for 5 minutes or until onions are translucent. Add cayenne (if using), salt, pepper, cumin, and oregano. Stir to incorporate and continue to sweat vegetables for another 2-3 minutes.
Stir in rice and cook an additional 5 minutes. Add pork, bacon, and chicken stock. Bring the mixture to a boil, then reduce heat, cover, and simmer for 20 minutes, or until rice is done, adding more stock if needed. Serve immediately. ½
