Savory Slow Cooker Vegetable Soup is a quick dinner recipe when you have leftover roast beef. Kids will love the classic veggies that fill this beefy soup.
Combine the beef, beef stock, bouillon cubes, tomato sauce and tomatoes, celery and onion in a slow cooker.
Add the frozen vegetables and spices.
Cover and cook on low for 6-7 hours or on high for 3-4 hours.
Stir well before serving.
Top with fresh parsley, if desired.

Notes
*If I do not have leftover roast beef, I use lean beef stew meat, trimmed and cut into small 1" chunks. Then I just add it to the slow cooker with the rest of the ingredients and cook on low for 7-8 hours or until the beef is fork-tender.
