In a large pot, add the spaghetti sauce, diced tomatoes, kidney beans, broth, and, if desired, cooked ground beef.
Add the diced carrots, celery, dried oregano, dried basil, garlic powder, and Italian seasoning.
Add spaghetti noodles to the soup. Continue simmering for 8-12 minutes until the pasta is tender. Season with salt. Add another splash of broth if needed to thin the soup.
