Salmon and new potatoes

1 kg new potatoes
2 tbsp olive oil
1 red onion
1 orange - zest and juice
handful of fresh dill (I used dried though)

Heat the oven up to 190°C. Wash potatoes and put into ovenproof dish, sprinkle with salt and olive oil, and bake in the oven for 15 minutes. Then add onion rings and bake for another 15 minutes. Then bring heat up to 220°C and add salmon pieces, sprinkle with orange zest and juice, also dill and freshly ground black pepper with some salt and bake for 8-10 minutes.
