Pre-heat over to 400 degrees fahrenheit.
In a medium bowl, combine the chickpea flour, salt, baking powder, turmeric, oregano and water. Mix until lump-free. Set aside.
Heat oil in frying pan at medium heat then add chopped vegetables and spinach. Cook for about 5-7 minutes or until almost soft.
Pour chickpea batter on top of vegetables and mix gently to evenly distribute vegetables.
Cook for about 10 minutes. You should see bubbles and edges of the frittata will harden. If, after 10 minutes, the edges are not slightly hard continue cooking for a few more minutes.
With an oven mit, place entire frying pan into the oven and cook for another 10-15 minutes or until you see the batter has completely solidified on the top.
Remove and let sit for 5 minutes.
Serve with toppings of choice!
