In medium skillet over medium heat, add 2 tablespoons oil and sweat onion and peppers 2 to 3 minutes then garlic and cook until translucent, about 5 minutes.
In a food processor, pulse together chick peas, red chili flakes, ground cumin, the egg, salt and black pepper to form a coarse consistency. Then add flour, parsley, and cilantro. Pulse until mixture starts pulling from the sides of the food processor.
Remove mixture to a large bowl and mix in the onion mixture. Chill falafel until ready to cook.
Roll falafel dough into 1-inch rounds.
In a thick-bottomed skillet heat ½ inch of canola oil over medium heat to 350 degrees F. Cook falafel balls a few at a time, until golden brown, about 5 minutes. Be sure to turn them so they do not burn or stick to the bottom of the pan. Drain on a paper-towel lined, oven-proof platter and sprinkle with salt while still hot. Then put into a warmed oven, to keep warm until all falafel are cooked.
Open the pita bread to make pockets. Place 3 to 4 falafels inside. Stuff with hummus, tzatziki, feta cheese, onions, cilantro, tomatoes and pepperoncini. Serve immediately.
