Grilled salmon in foil

Ingredients:

• 1 red onion, halved lengthwise and very thinly sliced
• 1 lemon, very thinly sliced, seeds removed
• 1 clove garlic, thinly sliced
• 1 salmon fillet weighing 700 g, center cut, skinless
• 55 g melted unsalted butter
• 1 tbsp dried Italian seasoning

Preparation:

1. Preheat grill to medium-high heat.
2. Mix the onion, lemon, and garlic with a generous pinch of salt and pepper. Spread the mixture down the center of a 2-foot piece of heavy-duty foil. Place the fish on top of the onion mixture, drizzle with butter, and sprinkle with Italian seasoning. Season with salt and pepper.
3. Fold the two long sides of the foil up to seal. Fold the ends of the foil inward and press to seal, leaving a little space inside for steam to circulate.
4. Place the package on the grill grate and cook for 10–15 minutes. Carefully, to avoid steam burns, open the package and check for doneness. It should be mostly opaque with a slightly pinkish center. Transfer the package to a cutting board and let rest for about 5 minutes.
5. Cut the salmon into 4 equal pieces and divide among 4 plates. Spoon the onion and lemons evenly over the fish, and pour over the juices from the foil.
