Preheat the oven to 400 ° F (200 ° C).

Lay parchment paper on two baking sheets. Set aside.

Peel the sweet potato and cut it into thin fries. Mix the fries with a drizzle of oil, garlic and chili powder in a bowl. Add salt and pepper to taste. Spread fries on a baking sheet.

Bake potatoes in the oven for about 20 minutes or until tender, turn them halfway through cooking time.

While the fries are baking, combine green onions, parmesan, coconut butter, mayonnaise, lime juice and chia seeds in a bowl. Set aside.

Place the white fish on the baking sheet. Pour the mixture over it.

Once the French fries are ready, remove them from the oven and turn the oven to "broil".

Put the fish in the oven for 10 minutes or until a golden crust forms on the fish.

Remove from oven and serve with sweet potato fries.
