Instructions

• Preheat the oven to 385°F (200°C). Prepare 2 large pieces of parchment paper (big enough to hold the fish) and fold over.
• Rub the fish filets with olive oil and season with salt.
• Layer the sliced onion in the center of each piece of parchment paper, then place the fish filets on top. Brush the fish with pesto, then top with the cherry tomatoes and sliced lemon.
• Fold the parchment paper over the filet and pinch the edges to seal the parcel tight.
• Place the parcels on a baking sheet, in the oven, and bake for 15 minutes.
• Once ready, remove from the oven and allow to cool slightly. Open the parchment paper carefully to release the hot steam, taking care not to burn yourself.
