Roast your potatoes & onions

  • Heat your oven to 220ºC/fan 200ºC/gas 7. Halve the potatoes, then peel the onions and cut each into 6 wedges.
  • Put the potatoes and onion wedges on a large baking tray lined with baking paper, spritz with cooking spray and lightly season. Roast for 20 mins.

Prep & poach the veg

  • Meanwhile, trim the green beans, dice the courgettes into 1cm chunks, and quarter the radishes.
  • Cook the prepared veg in boiling water for 3-4 mins, then drain.

Bake the salmon

  • Remove the tray from the oven, then toss the garlic paste through the potatoes and onions to coat. Create a space in the centre of the tray and add the salmon fillets.
  • Grate over the lemon zest, spritz with cooking spray and roast for 10-12 mins, until the salmon is cooked through and flaking.

Bring the zing!

  • At the same time, mix the horseradish and yogurt in a small bowl. Squeeze in the lemon juice (to taste), lightly season and stir well.

Plate up

  • Make a bed of the roasted potatoes and onions, green beans, courgettes and radishes, then top with the salmon fillets. Scatter over the pea shoots and drizzle over some horseradish sauce.
