Defrost the mahi mahi in a bowl of cold water with 1-2 tablespoons of lemon juice. If your fish is fresh you may skip this step. Once it is defrosted, drain the water from the bowl and poke a few holes in the mahi mahi. Place it in a large ziplock bag.
Next melt 3-4 tablespoons of coconut oil in the microwave for about 30-45 seconds. Pour 1 tablespoon of melted coconut oil in the ziplock bag, and sprinkle a dash of onion salt, garlic powder, cracked black pepper, rosemary & Italian seasoning. Let it sit in the fridge for about 10 minutes.
After 10 minutes, saute 1 tablespoon of chopped garlic and the chopped banana peppers, bell peppers and onions in 1 tablespoon of coconut oil for 2-3 minutes. Add the mahi mahi and saute for 5-7 minutes. Once done, remove the mahi mahi from the stove top and set to the side.
Pulse the coconut flakes and the panko bread crumbs in a food processor for 10 seconds. Next, pour a little coconut oil onto a piece of foil and sprinkle half of the bread crumb/coconut flake mix on top of the coconut oil.
Remove the mahi mahi from the pan and place on top of the coconut oil and bread crumb/coconut flake mixture that was placed on the foil and pour the remaining coconut oil on top of the mahi mahi. Sprinkle the remaining coconut bread crumb mixture all over the top of the fish.
On the side of the mahi mahi, pour in the remaining sauteed peppers, onions and garlic. Place the foil in a rectangular glass dish and place in the oven at 375 degrees F for 7-10 minutes.
Once done, remove from the oven & serve with your preferred side dishes. Enjoy!
