Preheat your grill to medium high heat. Peel your plantains and cut them in half, width-wise. Cut each half into fries, whatever your desired thickness is. I cut each plantain half into 6 fries.
Toss the plantains in a bowl with the melted coconut oil, ghee, or avocado oil. Place the plantains sideways onto your grill, so that they don't fall through, and cook until they begin to brown, approximately 5-6 minutes per side. Season with sea salt, dip into my chipotle aioli, and enjoy!
