Place the garbanzo beans, water and lemon juice in a food processor. Cover and process for a few seconds.
Transfer the mixture to a large bowl. Add the bread crumbs, egg and seasonings. Mix well, then shape into four patties.
In a large cast-iron or heavy skillet, cook patties in oil until lightly browned, three to four minutes on each side. Serve on toasted buns with cheese and your favorite toppings.
