Preheat a grill until hot and toast the crumpets until golden. Alternatively, toast the crumpets in a toaster until golden.
Mix together the avocado, tomatoes, red onion, chilli, coriander, lime juice and season.
Place the crumpets on a serving plate. Divide the guacamole between 2 crumpets. Spread the cream cheese equally over the other 2 crumpets and top with the smoked salmon. Sprinkle with crushed black pepper and the chives. Serve straight away.
