Knead the ingredients for the dough and let rest in the refrigerator for 30 minutes. Clean and finely slice the white cabbage. Cut the carrots into thin slices.
Fry the ham cubes in a little oil. Add white cabbage and carrots and fry briefly. Pour in the vegetable stock, reduce the heat and let the vegetables stew for 20 minutes. Stir every now and then.
Meanwhile, roll out the dough and place in a quiche tin (a large springform pan will do too). Pull up a small edge.
Preheat the oven to 200 ° C.
Take the vegetables off the stove and let them cool down briefly. Mix in the eggs, sour cream and the spices and pour the mixture onto the dough. Sprinkle with cheese and bake in the oven for 30 minutes.
