Instructions
In a large pot or Dutch oven over medium-high heat, heat the oil. Once hot but not smoking, add the beef, onion, and celery. Cook, breaking the meat into small pieces, until it is no longer pink and fully cooked through, about 7 minutes. Stir in the tomato paste, garlic, salt, pepper, oregano, and cayenne and cook for 30 seconds.
Add the tomatoes, potato, bell pepper, and Worcestershire. Pour in 3 cups of the broth. Stir to combine. Bring to a rapid simmer, then reduce the heat, partially cover the pot, and let simmer for 15 minutes.
Stir in the vegetables. Continue simmering, partially covered, until the potatoes are tender, about 10-15 minutes more.
If the soup is thicker than you would like, add the additional broth until you reach your desired consistency. Re-cover the slow cooker and let cook 5 additional minutes to warm through and allow the flavors to marry. Serve hot, sprinkled with cheese and chopped green onions.
