Friends have and Ive eaten them, but Ive never done it myself. Im pretty sure it was carrot, and yeah it was very tastey. Not real sure how dry it gets, or if you'd have to use extra wet in the recipe. I think its more a case of waste not want not, rather than specifically using it for a recipe. But for sure, it was good. I guess you could use apple, carrot, maybe even orange or celery if ya simply wanted to add texture and healthful goodness, not so much for flavour, but i dunno.
