For my tastes in Spain I did not find some particularly tasty traditional food, I know their paella is very famous and in all probability very good (if anyone doesn’t know, it’s their risotto), but we only came across seafood paella, which I personally don’t eat.
The shops sell similar food, but it bothered me that they didn’t have a variety of pâtés and salamis, we tried several different salamis but we didn’t really like any of them. But I have to admit they have very good prosciutto.
About 4 times a week we cooked our own meals, but when there was no time we also indulged in something in an inn or a fast food restaurant. Many times we ate at a nearby mall where they have plenty of choices.
