Turn your oven to 250C (480F). Line a rimmed baking sheet with paper.

If using the prosciutto wrap each salmon fillet with the prosciutto. Sprinkle with a little salt (or more salt if no prosciutto). Place salmon on the tray. Scatter around the frozen peas (no need to defrost). Halve a lemon and place on the tray.

Pop tray in the oven and set your timer for 10 minutes. Put your feet up.

When the timer goes, check the salmon - it may need a few minutes longer depending on your oven.

When the salmon is cooked, serve with herbs and pine nuts (if using) scattered over. And if using the pesto, place a generous dollop on top of each salmon fillet.
