1. Prepare the vegetables and set aside. Preheat a 10-inch skillet over medium heat.
2. In a small bowl, whisk together the chickpea flour, garlic powder, salt, pepper, baking powder, and optional red pepper flakes.
3. Add the water and whisk well until no clumps remain, approximately 15 seconds.
4. Stir in the chopped vegetables.
5. When the skillet is pre-heated (a drop of water should sizzle on the pan), spray it liberally with olive oil or other non-stick cooking spray.
6. Pour on all of the batter (if making 1 large pancake) and quickly spread it out over the pan. Cook for about 5-6 minutes on one side, until you can easily slide a pancake flipper/spatula under the pancake and it's firm enough not to break when flipping. Flip pancake carefully and cook for another 5 minutes, until lightly golden. Note: This pancake will take longer to cook compared to regular pancakes.
7. Serve on a large plate and top with your desired toppings. Leftovers can be wrapped up and placed in the fridge. Reheat on a skillet until warmed throughout.
