Preheat the oven to 375°F (190°C). Grease a 9-inch (23cm) pie pan (or line it with parchment paper).
Vegetables: In a large bowl, combine the broccoli, onion, greens, and salt. Toss to combine.
Batter: In a blender, combine the flour, water, yogurt, salt, kala namak, turmeric, cayenne, pepper, and oil. Blend until smooth. (Alternatively, whisk the ingredients together in a large bowl until smooth.)
Add the broccoli/veggie mixture to the batter. Add the cilantro, thyme, and dill and mix well. Pour the frittata mixture into the prepared pie pan and bake for 45 to 50 minutes, or until a toothpick inserted in the center comes out almost clean. The top will crack and get golden. Spray or brush some oil on the top of the frittata while it is still hot. Let it sit for 10 minutes before serving. Store refrigerated for up to 3 days.
