In a Dutch oven or saucepot, heat oil until hot; add one third each of the beef and pork cubes. Cook, stirring frequently, until brown on all sides, about 5 minutes. Using a slotted spoon, remove meat to a plate, repeat twice with remaining meat. Drain off any excess fat in pot; return all meat to pot. Sprinkle with black pepper and celery salt; stir to coat meat. Add beef broth and tomato sauce. Bring to a boil; reduce heat to low; simmer, covered, until meat is nearly tender, about 1 hour. Stir in chili powder, minced onion, cumin, paprika, garlic powder, brown sugar, sage, thyme and dry mustard; simmer until meat is very tender, about 1 hour. Makes 6 servings.
