Creating your falafel pita sandwich is straightforward when you follow these simple steps:

1. Prepare Chickpeas: Drain and rinse the soaked chickpeas. They should be soft but not mushy.
2. Make Falafel Mixture: In a food processor, combine chickpeas, onion, garlic, parsley, cilantro, cumin, coriander, cayenne, salt, pepper, baking powder, and flour. Blend until a coarse mixture forms.
3. Form Falafel Balls: Using your hands, shape the mixture into small balls or patties, about 1-2 inches in diameter.
4. Heat Oil: In a deep skillet, heat about 1-2 inches of vegetable oil over medium heat until hot but not smoking (approximately 350°F).
5. Fry Falafel: Carefully place the falafel balls into the hot oil, frying in batches. Cook each batch for about 3-4 minutes, or until golden brown and crispy. Use a slotted spoon to remove them and drain on paper towels.
6. Prepare the Pita: While the falafel is frying, warm the pita breads in a dry skillet or microwave for a few seconds until soft and pliable.
7. Assemble the Sandwich: Place the crispy falafel in the warm pita and top with shredded lettuce, diced tomato, cucumber, and a drizzle of tahini or yogurt sauce.
