Cook the ground beef in a large Dutch oven over medium-high heat until the meat is no longer pink, stirring to crumble, about 5-7 minutes. Transfer the ground beef to a plate or bowl; set aside. Drain off excess grease from the pot.
Heat the olive oil in the same Dutch oven over medium-high heat. Add the onion, carrots, bell pepper, and celery. Cook, stirring regularly, until the vegetables start to soften, about 5-7 minutes. Add the garlic; cook, stirring constantly, for 1 more minute.
Add the tomato juice, crushed tomatoes, chicken broth, Worcestershire sauce, salt, pepper, red pepper flakes, celery salt, and potatoes. Bring to a boil, then reduce the heat to low. Cover and simmer until the potatoes are tender, about 30 minutes.
Stir in the corn, lima beans, okra, pulled pork, shredded chicken, and ground beef. Continue cooking for at least 10-15 minutes (or longer, if you like the corn and other veggies really soft).
Stir in fresh parsley. Taste and season with additional salt and pepper, if desired. Ladle into bowls and garnish with additional chopped fresh parsley.
