Instructions

1. Rinse the potatoes and put them in a pan of lightly salted water. Bring the boil, then cook for approx. 15 minutes, or until tender. Drain, then cut them in half.
2. Meanwhile, heat the tomato sauce in another pan, add the stock and drained beans. Bring to the boil, then add the potatoes. Combine well and add more stock, if the sauce is too thick - you should have a thick stew, not a soup though.
3. Serve with chopped herbs.
