Step 1: Put the sesame seeds in a dry small fry pan, set over medium-low heat and toast the seeds, shaking the pan frequently, until golden brown, about 5 minutes. Transfer to a plate and let cool.
Step 2: Alternatively, put the seeds in a mesh spice toaster and hold it about 5 inches above a medium gas flame on the stovetop; do not place your hand too close to the flame. Shake the seeds in the toaster until golden brown, 30 to 45 seconds. Transfer to a plate and let cool.
Step 3: Using a mandoline or a sharp knife, cut the cucumber into 1/8-inch slices. Transfer to a colander, sprinkle with the 1/2 teaspoon salt and let stand for 10 minutes.
Step 4: In a small bowl, whisk together the vinegar, sugar and sesame oil.
Step 5: In another bowl, combine the cucumber, scallions, shiso and sesame seeds. Add the vinaigrette and stir to combine.
Step 6: Season with salt and pepper.
Step 7: Serve the salad at room temperature or chilled.
