1. Preheat oven to 400°F.
2. Gather and measure all ingredients.
3. Line a 9×12 pan with parchment paper. (Cut the parchment paper so it fits the pan almost exactly. This will make it easier to spread the flatbread batter to the edges, and then to peel off once baked.)
4. Place chia seeds, flaxseeds and water into a small dish. Stir, and set aside, allowing it to “gel” for at least 5 minutes.
5. Place plantain pieces, hempseed, coconut flour, turmeric, basil and sea salt in a blender or food processor.
6. Add in the chia seed and flaxseed mixture.
7. Blend mixture until it reaches a smooth consistency, scraping down the sides about halfway through (you don’t want any large pieces of plantain).
8. Spread mixture onto the parchment paper, covering the pan until it’s smooth and even.
9. Bake on the second shelf of the oven for 17 minutes.
10. Serve immediately.
