If desired you can seed the cucumber. I didn't. Thinly slice cucumber into half-moons; add to vinaigrette. Add daikon cut into thin strips. Add the mango, cubed.
Before serving, snip parsley into salad—the leaves retain their shape and won’t deteriorate too fast.
Gently toss salad together. Divide salad among 4–6 small salad plates. Note: I served on a bed of red leaf lettuce. Looked beautiful with the white, light green,and yellow of the salad.
