Preheat oven to 400°, warm 17 x 11 baking sheet in the oven so it gets hot.
Whisk together chick pea flour, water, salt, olive oil, oregano, garlic powder and apple cider vinegar. Set aside. It will be a loose batter.
Warm a sauté pan on the stove and add finely chopped onion salt pepper, sauté for about 1 minute, then add chopped basil.
Add this to the batter.
Remove the hot pan carefully form the oven and set down on heat safe surface. Drizzle about 3-4 tablespoons of olive oil in the bottom of the sheet pan. Pour the batter into the hot pan carefully, tilting to move batter to all corners.
