Peel and chop the onions. Clean, wash and chop the tomatoes. Heat 2 tablespoons of oil in a pan. Fry the ground pork and 3/4 of the onions in it. Add the tomatoes and sauté. Leave to cool.
Mix flour, milk, 4 tablespoons of water, some salt and 2 eggs. Heat the rest of the oil in portions in a frying pan. Bake 6 pancakes from the dough one after the other. Wash the parsley, dab dry and chop.
Fold 1 egg and parsley into the mince. Spread the mixture on the pancakes, roll up the pancakes and cut them into strips of about 4 cm width. Layer the pancake rolls in flakes in a greased, ovenproof dish.
Whisk cream and remaining eggs and season. Pour over the pancakes. Bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for about 20 minutes. Serve with salad.
