Preheat your oven to its highest setting.

Line a baking tray with foil. Place lemon slices on the tray in two lines and then trout on top of the lemon. Drizzle with a little oil and sprinkle with sea salt.

Pop trout in the oven. Set your timer for 5 minutes.

After 5 minutes scatter over the sage and almonds and pop the fish back in the oven for another 5 minutes.

When the second time is up, check the fish. If the flesh flakes easily when pushed with a fork and it looks cooked. You’re done. If not pop back in for another few minutes.

When the fish is cooked serve on 2 plates with the lemon, sage and almond and salad leaves on the side.
