Heat the oven to 180C/350F degrees.

Mix the walnuts, almond flour and herbs together in a bowl.

Dip the fish fillets into the beaten egg, then press into the bowl with the nut and herb mixture. Make sure that the fish is entirely covered and press any mixture onto the fish if needed.

Place the fish onto a baking parchment lined tray.

Scatter the garlic slices on top of the fish.

Drizzle the olive oil over the fish.

Cover the fish with silver foil and bake for 30 minutes.

Remove the silver foil and bake for a further 5 minutes.

Eat and enjoy!
