For the sugar snap pea avocado salad, first mix all the ingredients for the dressing and shake well, preferably in a well-sealed jar. It should be rather thick.
Pluck off the herbs. Cut the avocados in half, remove the pit and separate the flesh from the skin. Cut into wedges about 1/2 cm thick. Drizzle with a little lemon juice to keep them from browning quickly.
Spread the sugar snap peas and avocado slices on a plate. Drizzle with the dressing and sprinkle the sugar snap pea avocado salad with the herbs and lemon zest.
