Braise chuck roast for 4 hours at 325°F with au jus and enough water to cover halfway.
Meanwhile, add mixed vegetables, limas, corn, and chopped cabbage to a large pot. Cover with water and simmer.
Add diced tomatoes, whole tomatoes (crushed), and tomato paste. Stir.
Add a spoonful of Better Than Bouillon, dried chives, salt & pepper.
Shred the cooked roast and add both the meat and braising liquid to the soup pot.
Add more tomatoes or water to reach desired thickness.
Simmer 1–2 hours, tasting and adjusting seasoning.
Add a pinch of sugar if needed to balance acidity.
Serve hot with bread, cornbread, or crackers.
