Step 1

Preheat the oven to 200 degrees F (to keep cooked waffles warm).

Step 2

Combine the oil, cilantro, flour, parsley, baking powder, cumin, salt, coriander, cayenne, egg whites, garlic and chickpeas in a food processor and pulse until smooth.

Step 3

Lightly brush the top and bottom of the waffle iron with oil. Fill the waffle iron about three-quarters of the way full (some waffle iron should still be showing). Close the lid gently and cook until the falafel is golden brown and firm in the center, 6 to 10 minutes. Keep the cooked falafels warm in the oven or covered with foil on a plate while you make the remaining falafels.

Step 4

To build the sandwiches, stuff each pita half with a falafel. Add your choice of toppings, drizzle with the hummus and sprinkle with a few dashes of hot sauce.
