If you are using whole prawns, remove heads and peel them. Leave a few whole for decorative purposes, if you wish. I find that with medium size already cooked prawns, deveining is usually not necessary (it's hard to do + so small it's barely noticeably especially with sauce).

Mix together Sauce in a small bowl.

Toss prawns with Sauce.

Place a bit of lettuce in serving dishes. I like to use Martini glasses, but you can use any small serving vessel, or even small lettuce cups.

Top with prawns. Serve, garnished with lemon wedges and a sprinkle of parsley, if using.
