Toss lightly and serve or cover and refrigerate for 30 minutes
To toast sesame seeds:
Place the seeds in a small non-stick pan over medium heat for 3-5 minutes. Make certain you stir often and don't leave the pan! These go from done to burnt in almost no time at all! As soon as they start to brown a little, remove the heat and from the pan.
Can substitute regular cucumbers for the English cucumbers. Peel and seed regular cucumbers if using.
Reduce red pepper flakes if you prefer a milder taste.
If you refrigerate this salad before eating, the cucumbers will release some of their liquids and you will end up with more sauce. This does not affect the quality of the salad. You can drain before serving or just leave it at the bottom of the bowl.
