Boil the rice in 3 cups of boiling water. Clean the spinach, wash it well and cook it in a little water for about 5 minutes. After it has cooled, cut it finely and mix with 1 tbsp of butter, 1 hard-boiled and sliced egg, salt, pepper and nutmeg.
Cut the ham into pieces and mix it with the grated parmesan and cooked rice. In a buttered form, spread a layer of rice, then a layer of spinach and keep alternating. In the uppermost layer of spinach, make grooves and put 1 egg into each.
On top, place small pieces of butter and bake in an oven until the eggs harden.
