This classic Greek dip called htipiti is simple-to-make and bursting with flavour. the salty cheese and sweet peppers in the recipe make for a real winning combination. It can be made as part of a larger mezze plate- try serving it with hummus, toasted pita breads and olives for a starter that will stretch round lots of people. It is best eaten as soon as possible but will keep in the fridge for a day or 2 if well covered.
