Mix the cashew cheese, walnuts, chives, garlic granules and a pinch of seasoning together in a bowl, then cover and chill for 1 hr.

Tip the parsley into a shallow bowl and the chilli flakes or sumac into a second shallow bowl. Roll the chilled mixture into 20 small balls, then roll in the parsley or the chilli flakes, or sumac, until fully coated. Transfer the cheese balls to a tray and chill for 3 hrs, or until ready to serve. Any leftovers will keep in a jar, topped up with olive oil, for a week.
