Preheat oven to 375 degrees. Place 1 tablespoon of olive oil in a wide cast iron pan (recommended) or cake pan.
In a large mixing bowl, combine chickpea flour, sea salt, black salt, turmeric, baking powder, dill and cayenne pepper and stir. Add water and whisk until no lumps remain. Add 1 tablespoon olive oil and let the batter rest.
Add chopped greens, herbs, and sliced onions to the batter. Stir well and pour into prepared pan. Bake for 20-30 minutes, uncovered until batter is set and top is beginning to crack and brown a bit. Drizzle top with the remaining 1 tablespoon olive oil, and gently brush on. Return to oven for 5 more minutes.
Remove and let cool a bit before slicing and serving.
