I was looking for an alternative to regular burgers and i had a ton of carrots from the farmers market, so i thought i'd try this. It was great!I shredded thae carrot and celery, as suggested. We didn't have cornflakes so i decided to use a mixture of breadcrumbs and bran. After mixing half of it in i remembered that we had lays sour cream and onoin chips, so i crushed them up and added them. I also added shredded bell pepper and som season salt. Everyone loved them! Some reviewers used celery seed instead of the real thing, but i found that celery gave it a distinct flavor that went well with the carrot,don't make the substitution. If you want to grill these like (or with) regular burgers, put a sheet of foil over the grill and cook them on it for twice as long on each side.
