Summer Salmon Traybake

Place the potatoes in a layer on the bottom of a large baking dish. Add the onions in a layer. Then the asparagus and rosemary.

Drizzle with a good glug of olive oil, sprinkle with sliced garlic and season well with salt and pepper. Bake in the oven at 190C for 30-50 minutes or until the potatoes are tender.

Place the salmon fillets and tomatoes onto the vegetables, season again, then bake for a further 15 minutes before serving.
