PREP: Preheat the oven to 350F / 180C. Line a baking tray with a Silpat, foil or parchment paper.
SEASON: In a large bowl, add the plantain chips, coconut oil and garlic. Use your hands to gently toss the chips so that they are evenly coated. When the oven is hot, add the lemon juice and stir through the same way.
BAKE: Spread the seasoned plantain chips across the lined baking tray. Bake until just beginning to brown, about 8 minutes, then lay out on a paper towel for a minute or so to absorb any excess oil before serving.
You may wish to add sea salt to taste, depending on the plantain chips you use and how salty they already are.
