You can make these a day ahead. They need to be chilled anyway so they hold together well.
You can also freeze these with pieces of wax paper or plastic wrap between them. If so, cook from frozen rather than thawing first. Serve with regular hamburger buns; also lovely inside pita bread, perhaps with some mayonnaise and lettuce. Breadcrumbs: if you have whole wheat bread crumbs, use those for the extra taste; if not, white crumbs are fine. Chickpeas: Tin size of 400g / 13 oz. Don't worry if your tin of chickpeas is an ounce or two bigger, use it anyway. Fresh Cilantro: Don't rush out and buy if you don't have any. Try celery if you keep it frozen in fridge (see tips under celery), or anything else you might enjoy the flavour of, such as dried parsley, or omit entirely. Curry Powder: You can instead use 2 tbsp of curry paste if you keep paste to hand, or see ingredient entry for Curry Powder (highlight Curry Powder and click on it) for substitutes. Makes about 8 burgers.
