Mix the diced cucumbers, sun-dried tomatoes, capers, fresh dill and sliced scallions in a bowl.
Add the rice wine vinegar, olive oil, salt and pepper. Mix well, set to the side.
Mix the avocado cubes in a small bowl with salt and pepper.
Take the lid of a mason jar and spoon some avocado mixture in the bottom, about 1/2 an avocado per person.
Take the smoked salmon and roughly chop and place it on top of the avocado.
Spoon some of the tapenade on the side, or on top. Garnish with sliced green onions and serve with a lemon wedge to squirt over the top of the tapenade and the smoked salmon stacks.
