Melt the fat in a pan. Fry the gnocchi for about 5 minutes, turning them over. Season to taste with salt, pepper and nutmeg. Grate cheese and sprinkle over the gnocchi. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 5 minutes.
Wash the chives, dab dry and chop finely. Spread slices of bacon on the gnocchi and sprinkle chives on top.
