Story Behind this Recipe
My goal was to find an appetizer that satisfies an adult palate. So I mixed the watercress and wasabi that I like, (which I think have grown-up tastes) and combined them together.
When mixing in soft textured ingredients such as avocado, it's best to add them with a wooden spoon. If you mix the watercress early, it bruises and does not look appealing. Place it on the top of the salad and mix it when you start eating.
