Pork tenderloin in puff pastry

First you clean and chop the mushrooms. Smother them in onions.

Salt and pepper the pork tenderloin and sear it in a frying pan until it is golden brown. Then let the meat rest.

Roll out the puff pastry and place the cheese slices on top.

Place the sliced mushrooms on top of the cheese and add the pork tenderloin on top.

Wrap the dough so that you wrap the meat properly. Then brush it with beaten egg.

Bake the pork tenderloin in a preheated oven at 180 degrees for about 25 minutes, but the time can vary depending on your particular oven, so it's a good idea to keep an eye on when the pastry gets golden brown.
