If you like the spead could be served as a dip with people dipping in the tortilla chips or alternatively some crudites. You can make the cheese mixture up to six hours ahead, cover with clingfilm and refrigerate. Remove from the fridge about 20 minutes before using to let it soften. Dollop over the tortilla chips just before serving.
