Recipe for Czech buckwheat pancakes?

I was just in the Czech Republic at a Renaissance festival. They made "Pohankove Placky" at one booth--a buckwheat dough rolled out flat then cut into circles like tortillas and cooked on a grill, then topped with garlic spread and leeks. They were fabulous. Any ideas on a recipe? They seemed to be unleavened and we were told they had rosemary in the dough. Slightly thicker than a tortilla, not crispy. I have no other clues about ingredients! Thanks.
