For the quiche, finely chop the leek and place in the steamer with diced bacon and spices for approx. 8 min at 100 °C, allow to cool. Line a high baking tray or a pie dish with strudel dough and place the filling on top. Whisk eggs with whipped cream and pour over it. Sprinkle with grated cheese and place a grid over the top. Bake intensively at 170 °C for about 45 min (on lowest setting).
The quiche is best served warm and with fresh salad.
