This is a dairy-free, gluten-free fish pie. It can be simplified by missing out some of the ingredients such as the fennel, capers and peas if you don't have them. The kale is a must though as it gives some crispiness to a mushy pie - yum!
Remove kale leaves from stalks and bake for 45 mins on a low heat in the oven, drizzled with olive oil and a bit of salt.
Cook the potatoes in boiling salted water til tender, drain and rinse. Mash with some olive oil and coconut milk, adding salt, pepper and nutmeg.
Place the fish in a baking tray, lightly greased.
Heat the onion half in a pan with fish skin and fennel stalks (optional), along with the coconut oil. Add the bay leaves, salt and pepper. Simmer for a few minutes. Add the coconut milk and gently simmer for about 25 minutes to make a broth. Then sieve and return the broth to the pan adding the flour to make a paste.
Add the chopped fennel to the dish with the fish along with the capers and a little seasoning. Add the peas if you have any. Pour the sauce over the fish. Top with the mash. Cook for 45 mins at 180C and about 5 mins before the end add the crispy kale to top the mash.
