Prawns that were cooked, shelled and deveined were on sale today, so I bought them and made up this recipe because I couldn't find anything on the net. Anyway, it got five-plus stars from everyone at the table, so I thought I'd post it before I forgot it. It was so easy and I'm sure you can 'juggle' the portions and the ingredients. By the way, Lebanese cucumbers are the long, thin ones (don't know what they are called in the USA—would appreciate it if you can tell me). Good luck and enjoy.
