Put a teaspoon of Wakame flakes in the bottom half shell of each oyster then place on oyster top.
Carefully cover each oyster with the cheese mixture and sit on a baking tray, keeping the shells tightly placed together so that they do not slide around.
Preheat the oven to 180 deg celcius. Put the tray of oysters in the oven for 8 minutes or until the cheese is golden brown and bubbling.
Carefully transfer the cooked oysters to serving plates and serve with the lemon wedges.
