Add chickpeas, onion and garlic to a food processor. Pulse until combined - you still want it to be chunky.
Add cilantro, parsley, cumin, coriander, red pepper flakes, salt & pepper to the food processor and pulse until everything is combined - you want it to be slightly smoother, but still a little chunky.
Sprinkle baking powder and flour over the mixture and pulse a final time. You want the mixture to form into a ball that is not too sticky.
Line a baking sheet with parchment paper. Sprinkle some flour on your hands and form the dough into 12 balls. Place them on the baking sheet and flatten into thick discs.
Add an inch of oil to a pan and heat to 375 degrees. Working in batches, add falafel to the pan. Once browned on the bottom, flip and brown the other side. Place on a paper towel lined plate and allow excess oil to drain.
Repeat with remaining falafel.
Serve in a sandwich, over a salad or individually with Tahini Dressing. Store in the fridge in an airtight container for up to 5 days.
