Add all meat again. Season with salt, pepper, 1⁄2 tsp. sugar and 1 tbsp. oregano and cumin. Add tomato paste and sweat briefly. 3⁄4 Add 1 l water and tomatoes together with the juice. Chop the tomatoes a little bit, stir in the stock. Add beans, bring to the boil, cover and braise for approx. 1 1⁄2 hours at medium heat, stirring occasionally.
For the topping, clean, wash and finely dice or chop the radish. Clean and wash spring onions and cut into fine rings. Wash parsley, shake dry and chop finely. Wash limes hot, dry and cut into slices.
