Heat oven to 180C/160C fan/gas 4. Cut the manchego into 12 cubes or oblongs. Fold a slice of chorizo around each piece of cheese and push a cocktail stick through the middle to secure it. Push half a grape on to one side, then transfer skewers to a baking tray and cook for 5 mins. Cool.
Wrap each mozzarella ball in basil, top with half a slice of prosciutto and push a skewer through. To serve young children, slide everything off the skewers.
