Red Thai chile packs a punch in a tiny form, so to lower the heat a bit, cut in half, remove the seeds and mince. You can also use any other type of spicy chile you prefer; just mince and toss with the salad dressing. There are many ways of smashing cucumbers: you can smash them with the flat side of a large knife (just like you are crushing a garlic clove), rolling pin or even a meat mallet.
