Take your puff pastry sheets and roll them thinner (1/8 inch is great). Cut each sheet into 4 even pieces.
02 -
Spread a teaspoon of Dijon on one side of each square. Toss on 1 tablespoon of cheese, then the ham, and finish with another tablespoon of cheese. Make sure to keep the edges free.

Wet the edges lightly with water, fold the pastry to form a triangle, and pinch the edges together. Seal well with a fork around the edges.

Put the pastries on a baking sheet lined with parchment paper. Keep them in the fridge for 15-30 minutes. Preheat the oven to 400°F while you wait.

Give the top of the pastries a brush of egg, cut a few little slits (steam needs to get out), and sprinkle on some fresh thyme if you like.

Pop the pastries into the oven for 15-20 minutes. They should be golden and crisp. Serve them warm for the best experience!
