Chop the ingredients.  In a food processor, pulse the parsley, cilantro, garlic, and red onion about 10 to 15 times or until well chopped.  Add the cumin, salt, pepper, lemon juice, and chickpeas and repeat until minced.

Make the burger mix.  Either in the food processor or in a bowl, combine the ground turkey with the minced falafel ingredients.

Make the patties.  Divide the mix into 6 equal portions in a rough ball shape (5 ½-ounce patties.)  Place between two pieces of parchment paper and press down with a plate or saute pan until the patties are ½-inch to ¾-inch thick.  You can also form the patties by hand without parchment paper and jut wetting your hands with a little water to keep the mix from sticking to your hands.

Grill the falafel burgers.  Over medium-high heat, grill the burgers 5 minutes on each side until cooked through.  When the burgers are about half-way done cooking on the second side top with any cheese.

Assemble.  Stack the cooked burgers on toasted whole wheat buns, feta cheese, tzatziki sauce, and pickled onions.
