For the vegetable strudel, mix the cooked vegetables and the grated cheese with the creme fraiche. Mix with the herb salt, pepper, nutmeg and parika powder.
Remove the puff pastry from the foil. Cover with the vegetable mixture so that you can still roll it up. Before you start rolling it up, moisten the free dough with water so that the dough will then hold together better.
Then place the strudel on the greased baking tray. If you make 2 or more strudels, it is best to put some baking paper between the strudels.
Then brush the strudel with whisked yolk and put in the preheated oven at about 180 degrees for 30 – 40 minutes.
