Add chickpeas, cilantro, parsley, onion, flour, lemon juice, baking powder, cumin, salt, black pepper and garlic to a food processor.  Pulse until the mixture reaches a coarse crumb texture, stopping partway through to scrape down the sides of the bowl if needed.  Transfer mixture to a sealed container and refrigerate for 1-2 hours or until chilled.

Lay a large sheet of parchment paper on a work surface.  Using a spoon or a medium cookie scoop, measure out 2 tablespoons of the dough and roll it into a ball with your hands.  Place the ball on the parchment paper, and gently flatten it slightly with your hand so that it is about 1/2-inch thick.  Repeat with the remaining dough until all of the falafel disks are prepared.

Heat oil in a large cast-iron or heavy-bottomed skillet over medium-high heat until it is shimmering.  Carefully transfer 4 or 5 falafel disks to the hot oil and fry for 2-3 minutes per side, or until both sides of the disk are browned.  Transfer to a paper-towel lined plate to drain.  Repeat with the remaining falafel disks, adding extra oil to the pan if need be.

Serve the falafels immediately while they are warm and crispy.  Or freeze in a sealed container for up to 3 months.
