Let me start with saying I've never tried this recipe, but being Croatian and growing up with this food, I can maybe offer an insight in why some people had issues with it. Lepinja is a traditional "bread" served with chevapcici, which is a minced sheep meat or beef meat (never pork) and it's origin is in Bosnia. Submitter has the ingredients right and has described the making process very well. However, you need to preheat your oven to as high as it will go prior to putting lepinja's in. Also, separate dough into flat rounds. You can make a ball and flatten it... Very hot oven will make the lepinja "split" and puff in the middle, making it easy to cut it open.
