Heat oven to 220C/fan 200C/gas 7. Place four fillets, skin side down, in a roasting pan. Season, then top with the lemon slices, mixed herbs and finish with the almonds. Cover with the other four fillets, skin side up, season the skin and drizzle with olive oil. Bake for 15-20 mins until the fish flakes easily. Serve with a green salad and some new potatoes.
