Dab the cod with a paper towel until dry, sprinkle them on both sides with sea salt, and fresh black pepper, and squeeze out a lemon over the cod.
In a deep, flat plate combine the almond flour, oat fiber, garlic powder, onion powder, paprika, fish spices, and salt and pepper until well incorporated.
Heat up a skillet with some olive oil and carefully place the cod in the skillet. Do not touch the fish until it's time to turn them around. When they are done remove from the heat, set them aside, and cover them to keep warm.
Add the butter to the skillet and allow it to melt. Now add in the garlic, onion, and fresh dill and keep stirring until it smells aromatic and the garlic and onion have caramelized. Drizzle the sauce over the cod.
Plate and serve with a fresh slice of lemon on the side.
