Preheat cast iron skillet or other heavy bottomed pan over medium high heat. In a large bowl, toss potatoes with paprika, mustard powder and salt and pepper to taste. Drizzle liberally with olive oil. Toss to coat all potatoes evenly. Add potatoes to pan and shake to distribute. Cook for several minutes, shaking pan often to sear all sides. After several minutes, add beef broth, onions, garlic, and green pepper and bring to a boil. Cover. Reduce heat to medium and cook until potatoes are just fork tender about 6 to 8 minutes. Fold in corned beef, leaving varied sized pieces for texture. Re-cover and turn off heat to allow the corned beef to heat through. Taste and re-season to taste as desired and drizzle with olive oil before serving Serve with hot buttered or plain toast, biscuits, whole wheat tortillas or other bread as desired. *You may use deli style corned beef if you wish.
