Prepare your workspace by dusting it lightly with flour.
Once the potatoes are baked, remove the flesh from the skins and mash while warm.

Cut these into bite-sized pieces and lightly press with a fork to create ridges.
In a pan, heat olive oil and sauté the gnocchi for about 2 minutes per side until golden.
