If so, you shouldn't cook them. Just slice and add to your fav salad. I use a mandoline.
You can also do a quick brine and make a side dish. This is an easy & tasty Korean recipe that David Chang uses in one of his restaurants.
You can drain the water that pools and add a bit of garlic and/or hot pepper flakes for additional flavor.
