Many years ago after an invited seminar talk at ISTA in Vienna we went with my host Tamas Hausel and some of his group for dinner to a Croatian restaurant. I had fish I think and a side dish of potatoes and chard, which I really loved. I have been trying to reproduce it from memory ever since. I found out later (while on vacation in Lussinpicolo) that it is actually a standard traditional dish in Croacia known as blitva (which simply means chard).
