In a food processor, add chickpeas, parsley, onion, garlic, and seasoning. Blend until crumbly but not chunky.
Line a Sheet Pan with parchment paper and brush with olive oil. Using Prep Pro Scoop (1⁄4 cup) or a large ice cream scoop, form chickpea balls. Place on lined sheet pan 2" apart and flatten. Bake until browned on top, about 30 min.
