Whisk eggs and 1 pinch of salt. Add 180 g flour and 160 ml milk bit by bit and mix to a smooth dough. Cover and let it swell for about 20 minutes.
Meanwhile peel onions and garlic and cut them into fine pieces. Heat 1 tablespoon of oil in a large frying pan. Fry the onions and garlic for about 3 minutes, turning them over. Add spinach and 75 ml water, bring to the boil, cover and simmer for about 15 minutes.
Season with salt, pepper and nutmeg.
Melt the fat in a pot. Stir in 15 g flour, sweat briefly. Add 125 ml milk and broth bit by bit while stirring. Bring to the boil, simmer for 6-8 minutes, remove from the heat. Add cream cheese to the sauce and let it melt.
Season to taste with salt, pepper and nutmeg.
Heat 1 teaspoon of oil in a coated pan (18 cm Ø). Put about 1/4 of the dough into the pan, bake to a pancake, turning once. Bake 3 more pancakes from 3 tsp. oil and the remaining dough.
Put 2 slices of ham on each pancake. Spread approx. 1/4 spinach as strips in the middle of each pancake. Roll up the pancakes and cut them into 4 small rolls. Pour some cream cheese sauce into an ovenproof dish.
Place the rolls on top with the cut side facing upwards. Pour on the rest of the sauce. Grate the cheese, sprinkle over it and bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for 20-25 minutes.
Remove the casserole from the oven and sprinkle with parsley if necessary.
