The sesame and mayonnaise dressing is an imitation from the restuarant "Bikkuri Donkey" and goes really well with shredded vegetable salad.
I like the salad they serve at Bikkuri Donkey, so I tried to make it at home.
Just soak the veggies in water to make them crunchy. Then, when you're draining them, put a plate or something under the sieve, chill in the fridge for a while and they'll be nice and crunchy.
Enjoy Japanese food around the world.
