I did a search, I just typed in Recipe for Garbanzo bean burger, a bunch came up. Here's one. I certainly can't vouch for it, since I've never tried it. It does sound yummy though.
2 cups mashed garbanzo beans (chickpeas)
1 stalk celery, diced
1 carrot, grated
1/2 onion, minced
1/2 tsp garlic powder
1/4 cup flour
salt and pepper to taste
oil for frying
PREPARATION:
Mash together all ingredients, except oil, thoroughly. Form into patties and lightly fry on each side in oil until golden brown. You can also barbecue these veggie burgers on the grill.
