Preheat the oven to 425°F.
Prepare two baking sheets with parchment paper and set aside.
Open the cans of chickpeas, rinse, drain, and add to the food processor.
In a small bowl, mix together the powdered egg substitute to the package direction and set aside to thicken.
Next add the fresh parsley, lemon juice, garlic, onion, flour, salt and pepper to the food processor.
After the egg substitute has thickened, add to the beans.
Pulse everything together to a smooth texture.
In a small bowl, mix together the panko breadcrumbs, oil, salt and pepper.
Scoop the size of the bean mixture you prefer, anywhere between 1 to 2 Tablespoons, and roll into a ball and drop into the panko mixture.
Gently coat the ball with the panko and place onto the baking sheets.
Continue until all the batter is formed into balls and coated.
After filling the baking sheet slightly press each ball with a bottom of a glass to form a patty.
Place both baking sheets into the oven and bake for 15 minutes.
After the 15 minutes, flip the patties, rotate the baking sheets and continue to bake another 15 minutes.
Remove from the oven and serve as a burger or as a appetizer.
