Make a yeast dough from flour, yeast, sugar, salt, water and oil. Cover with a cloth and let rise for 30 minutes.
In the meantime, fry the diced ham in a large pan. Add the washed and cut into rings and sauté for about 10 minutes.
Mix the eggs with the spices and crème légère, add the cheese and mix well. If you like it spicier, add a pressed clove of garlic.
After the resting time, dust the dough with flour, roll it out and place on a baking tray lined with baking paper. Add the egg / cheese mixture to the leek and distribute everything evenly on the dough.
