Heat the oven to 220C / 200C fan.

Cut the potatoes into 2cm chunks, toss with half the oil, salt and pepper, and spread over a large tray. Roast for 20 minutes.

Meanwhile cut the broccoli into florets and toss with the remaining oil and the smashed garlic cloves.

Pull out the tray, push the potatoes to one side, and add the broccoli. Nestle the salmon fillets among them, skin-down.

Season the salmon, top each fillet with a lemon slice, and return to the oven for 12-14 minutes until the salmon flakes at the thickest point.

Squeeze over the remaining lemon and serve straight from the tray.
