1. Preheat the oven to 180c and line a baking tray. Place the red onion, asparagus, peas and 3/4 of the sliced lemon on the tray.
  2. Cut 2 slices into each side of the two fish and place some lemon and parsley inside them. When you do this, try to not cut through the backbone with the knife as it will then make it harder to pull the flesh off the skeleton.
  3. Place the two fish on the tray and drizzle everything with olive oil and sprinkle with salt and pepper
  4. Cook for 15-20 minutes.To check if it is cooked, just get the knife and you should be able to easily pull the flesh away from the bones.
  5. To easily get a fillet off the fish, look for the subtle line down the side of the fish’s body. Slice along here and then peel the flesh away from this cut (outwards) The flesh should easily come away. Here is a video if you need it! (Just keep the skin of the fish on!)  https://www.youtube.com/watch?v=TSOkPmv7fjI 
  6. Serve with veggies/sides and enjoy!
