Salmon and brussel sprout gratin

Once again I've got this recipe from http://undervarttak.blogspot.se. I think I'll be making quite a few other recipes from this website/blog this weekend. They have so many good ones.

Ingredients
serves 2-3
500 g salmon fillets
500 g fresh brussel sprouts
2 garlic cloves
1 lemon
50 ml chopped parsley
100 ml coconut milk
Salt and pepper to taste
Olive oil

Preheat the oven to 225 degrees Celsius.
Clean, half and pre-boil the brussel sprouts for about 4 minutes.
Pour out the water and pour a little bit of olive oil on them. Crush the garlic over the sprouts and mix around. Add in the parsley, salt and pepper and mix.
Get the skin of the salmon fillets and cut into cubes. Add the salmon to the brussel sprouts and carefully mix around. Squeeze in the juice from the lemon.
Pout everything into an ovenproof dish and pour over the coconut milk.
Cook in the oven for about 20-25 minutes.
