Cut the remaining puff pastry, cheese and ham into approx. 2.5 - 3 cm wide strips. Cut the tomatoes into 2 or 3 pieces, depending on their size.
Now lay out the outer edge alternately with ham, puff pastry, cheese, puff pastry, tomatoes, puff pastry, etc. in rounds. Season with salt and pepper. Drizzle some olive oil over it and brush with a little milk.
Bake in the oven preheated to 200 ° C for approx. 20-30 minutes until golden brown.
