Heat a 12-inch cast iron Dutch oven over medium heat using a campfire, camp stove or charcoal briquettes.
Heat oil in the pot, season the pork chops with salt and pepper then add them to the Dutch oven, turning them to brown on both sides. Work in batches, if necessary.
Remove the chops from the oven.
Place rice, Worcestershire sauce and beef broth in the bottom of the oven and stir to combine.
Add the pork chops back to the pot, placing them on top of the rice.
Cover chops with bell pepper, onion, garlic and tomatoes then sprinkle the oregano over everything.
Cover and simmer over medium-low heat until the pork chops are cooked through and the rice is tender, about 20 – 30 minutes.
