I just threw this together in the crock pot. It came out delicious and so tender! And yes, the tomato soup adds just a hint of tanginess. When I made this I put 2 London Broil roasts in the crock pot. One was for dinner, and the other I froze with the remaining broth. Then later I made my delicious "Hearty Vegetable Beef Soup" with it. The beef just fell apart!
