Preheat oven to 300 degrees F. Wash your plantain. Using a sharp knife, cut the top and bottom off of the plantain and dice it into three sections. Cut the peel along the ridges of each section. Peel off the peel.

Install the 'fine slicing' blade into a food processor. Slice the plantain sections.

Line two baking sheets with parchment paper. Lay out the plantain slices on the parchment paper. Make sure the slices do not touch.

Melt the coconut oil and drizzle it over the slices. Generously sprinkle the garlic salt and powder over the slices.

Place in the oven and bake for 30 minutes with 'speed bake' or convection turned on. The chips are done when they are crispy and just starting to turn golden brown.
