Firstly, make a quick flavoured mayonnaise. Put the mayonnaise in a small bowl. Add the lemon zest and a twist of black pepper and stir together. You can add a teaspoon of dill pickle juice to loosen it slightly, but this is optional.
Slice the bread and arrange on a platter. Butter each piece and spread a little mayonnaise on each slice.
Arrange the leftover turkey, or other meat, on each slice of bread.
Top with sliced radishes, pickles, tomatoes, boiled eggs and kabanos.
Finally, garnish with cress and lots of fresh dill.
