Add the chickpeas to a blender, nutribullet or food processor, blend until the texture is chunkier than a fine crumb. Place into a large bowl.
Add the onion and garlic to the blender, blend until a paste forms. Add the green peas, ground cumin, ground coriander, cumin seeds, lemon and fresh herbs; blend until combined. (If you are blending in a nutribullet you will need to be patient and may need to stir and shake intermittently to make sure all the ingredients are blended together).
Add the herb and pea mix to the chickpeas, add the flour and sesame seeds, mix well to fully combine all of the ingredients. Using a spoon and your hands, form approximately 20 small falafels. Place on a large tray and into the oven for 30 minutes, rotating halfway. Falafels should be golden and crisp on the outside when cooked.
