Baked Cod with Potatoes

Peel the potatoes and slice them very thinly into rounds (if slicing by hand and they aren't thin enough, parboil for 2 minutes).

Cut the cod fillet into pieces and thinly slice the onion into half-rounds.

Lightly grease a baking dish with olive oil.

Layer half of the potatoes in overlapping rows, lightly salting each layer and sprinkling with oregano.

Add the onion and fish, season with salt, pepper, and oregano.

Tuck small pieces of cream cheese into the gaps around the fish and scatter with sliced olives.

Pour over the white wine and drizzle with olive oil.

Top with the remaining potatoes, season with salt and pepper, drizzle with olive oil, and finish with oregano and capers.
