Preheat your oven to 400°F and line a baking sheet with parchment paper.
Place the parsley in a food processor fitted with an s-blade. Pulse a few times, until the parsley is chopped.
Add the chickpeas, garlic, tahini, cumin, salt, and pepper to the food processor. Process until everything is mixed together, and the mixture resemble a chunky paste. You may need to stop and scrape down the sides of your food processor once or twice. Pulse in the chickpea flour.
Form the burgers into four patties. If you have one, a ring mold will help shape them, but forming patties by hand is completely fine.
Bake the burgers for 10-12 minutes. Flip them and bake for an addition 8-12 minutes. They should be golden brown and firm.
