Make sure all ingredients are dry before you put them in the food processor. Add garlic, onion, leek, parsley and cilantro to a food processor. Pulse until onion and garlic are pulverized.
Add chickpeas, baking soda, coriander powder, cumin, salt and pepper to the food processor. Process until mixture is well blended, but careful not to over blend.
Refrigerate mixture for at least a half an hour (an hour tops)
Form mixture into small, flat patties. Roll in sesame seeds. Add extra virgin olive oil to a skillet or cast iron pan (enough oil so there is a half an inch in the pan). Heat the oil on medium heat.
Fry patties until they are brown on both sides. Drain on paper towels. Serve immediately!
