Directions
- Slice small baguettes in half. Spread both sides with mayonnaise mixed with plenty of freshly ground black pepper, mustard, lemon zest and juice.
- Pile warm braised beef (or use whatever leftover meat and the all-important gravy, you have to hand) on one half and sauerkraut on the other. Pour braised beef gravy over both halves, close and cut into serving-sized chunks you can dip into extra gravy as you are eating.
