Perfect as an appetizer for a dinner party. Looks good, tastes good, no cooking and if you want to you could maybe substitute store bought guacamole. The most fiddly bit is cutting the smoked salmon into circles.
Take 1 ripe avocado and mash it with a fork. Add 1/2 tbsp. freshly squeezed lemon juice, 1 tbsp. finely chopped shallot, salt and freshly ground black pepper.
Using a smallish cookie cutter, cut 8 small circles of smoked salmon. Sandwich 1 tbsp. avocado mixture between the salmon circles.
