1 tablespoon vegetable oil

2 tablespoons minced green bell pepper
¼ cup ground beef
¼ cup ground pork
2 cups water
1 14 ounce can beef broth

Heat vegetable oil in a large saucepan over medium heat. Sauté chicken gizzard in the oil for 4 to 5 minutes until cooked. Remove gizzard from the pan and let cool. Finely mince the gizzard after it has cooled. Combine beef and pork in bowl, mix with your hands until well blended.  Add bell pepper to the saucepan and sauté it for 1 minute. Add meat mixture to the pan and cook until brown. Mash meat into tiny pieces as it browns.  Add water and beef broth to the saucepan, then immediately whisk in cornstarch and flour.  Add remaining ingredients and bring to a boil.
