Green Salad with Marinated Cucumber and Red Onion

This salad is tasty and refreshing. It requires a little advanced planning since the cucumbers, onions, and radishes must marinate for about half an hour, but otherwise it's super easy. The crunchy vegetables are marinated until just slightly pickled, and then everything is tossed together with greens so that the marinade becomes the salad dressing. I love this treatment for cucumbers and onions, which neither of which I love just tossed raw into salads. Marinated, they're much tastier and have a better texture. We found the original recipe to be a bit heavy on the onion, so the amount is reduced below; if you're particularly fond of onion, feel free to use a whole small red onion.
