Heat the oil in a large soup pot over medium-high heat.
Season the beef with salt and pepper. Add the beef to the soup pot and brown in the hot oil, stirring frequently (do this in batches if necessary).
Add the onion, garlic, celery, and carrots; cook and stir about 4 minutes or until the vegetables begin to soften.
Add the soup mixes, water, and potatoes; bring to a boil. Change heat to medium-low and simmer 45 minutes to 1 hour or until beef is tender.
Add in the corn and green beans and cook until the beans are tender. Adjust the seasoning to taste with salt and pepper if needed.
