Start by soaking the dried chickpeas in a large bowl of water overnight. This softens them and makes blending easier.
After soaking, drain and rinse the chickpeas. In a food processor, combine the soaked chickpeas, chopped onion, garlic, parsley, cilantro, ground cumin, salt, black pepper, and sesame seeds. Pulse until the mixture is coarse but holds together when squeezed.
Transfer the mixture to a mixing bowl. Sprinkle the baking soda over the mixture and gradually add cold water, mixing until you achieve a consistency that allows you to form balls.
Using your hands, form the mixture into small balls or patties, about the size of a golf ball. Place them on a plate or baking sheet lined with parchment paper.
In a frying pan, heat about 2 inches of oil over medium heat. You can test if the oil is ready by dropping in a small piece of the falafel mixture; it should sizzle immediately.
Carefully place the falafel balls into the hot oil, being cautious not to overcrowd the pan. Fry for about 3-4 minutes on each side, or until they are golden brown and crispy.
Your Classic Crispy Vegan Falafel is now ready to serve! Enjoy them in a pita with fresh veggies or as part of a larger meal.
