Add the juice of the 2 lemons, the olive oil and melted butter to a bowl and mix.
Then mix the flour and spices in a separate bowl.
Dunk the fish fillets (cut to portion size) firstly into the lemony mixture, then roll in the flour mixture to coat and place straight into a baking dish.
Add the crushed garlic and parsley to the lemon mixture and pour this over the fish.
Place the fish in the preheated oven and bake for around 12-15 minutes, until the fish is cooked through.
Serve with some delicious green vegetables such as kale and green beans.
