My mother was born in Hungary and one of the delicacies she made as a part of a recent authentic Hungarian dinner was a beet salad (in addition to sour cherry soup, my favorite in Hungarian cuisine, and chicken paprikash and dumplings). They make beet salad with a sweetish white vinegar dressing or marinade.
What is popular now are beet chips, either as a stand alone product or in veggie chip assortments with sweet potato and taro. The Big Y has a whole veggie chip stand where they sell beet, carrot, string bean, kale and assorted variety packaged veggie chips. I like the beet chips a lot. The kale chips are pretty good too.
