Drain the garbanzo beans, but reserve ¼ cup of liquid.
Add the beans, reserved liquid, green onion, parsley, garlic, flour, baking powder, cumin, and salt to your food processor. Pulse until relatively smooth (look for the texture of guacamole).
Spray the grill of the waffle iron, top and bottom.
Scoop ½ cup (or use a #12 scoop) of falafel filling into the center of your iron, and close the lid. Cook for 3-5 minutes, or until the green light on your waffle maker turns on. Most waffle makers will tell you when the food has been cooked to temperature.
Repeat 3 more times to get a total of 4 waffles.
