Cheese and tomato is one of the finest pairings ever. Here I’ve upped the ante a little by wrapping the haloumi in vine leaves before baking until soft. You can find vine leaves preserved in brine at specialty food stores or online (make dolmades with any leftovers). To use fresh vine leaves, choose only new-season, fresh leaves as older ones are too tough. To prepare, trim the stalks off and cook in boiling water for 5 minutes before draining and rinsing in cold water. Dried oregano can be used in place of the fresh oregano in the salad if that’s what you have, oregano being the one herb I find is just as good dried as fresh.
