Put the plantain chips in a food processor and finely grind. Place into a shallow bowl.
Dip the top of the fish into the whisked egg, letting any excess drip. Then place the top of the fish into the bowl with the crushed chips. The top of the fish should be well coated. Repeat with remaining pieces of fish.
Bake at 500F for 10-12 minutes or until the fish easily flakes.
This recipe calls for only one side of the fish to be coated with plantain chips, but you can easily double the amount of plantain chips to coat both sides.
