Divide tomatoes in half; add half to blender or food processor and blend until they become a smooth liquid. Dice the other half roughly. Add diced tomatoes and tomato juice to the pan with the veggies and cook down until desired consistency is achieved; 15-20 minutes for a more loose soup/stew like consistency, 30 minutes for a thick, spread-like consistency.
