To make the meatballs, mix all the ingredients in a bowl. Make sure the onions are finely chopped and bread slice soaked in water.
Stir the mixture well, form walnut-sized meatballs from it (or a bit larger ones if you like).
Arrange them in a small tray - I used the lid of a glass cook pot.
To make the Bechamel Sauce, heat a little oil in a pot and melt the butter. Then add the flour and braise well.
Once ready, pour it into the pre-boiled milk and stir until thickened. Add the spices. Pour the Bechamel over the meatballs and sprinkle generously with cheese.
Bake in a preheated 392°F (200 °C) oven until fully ready. Sprinkle with finely chopped parsley at the end.
