A Shanghai favourite. 猪肉荠菜馄饨 zhū ròu jì cài hún tún - Pork and Shepherd's purse (荠菜 jì cài) wontons with wilted, shredded lettuce (生菜 shēng cài).
Wontons were cooked in a peppery chicken broth and the lettuce thrown in for the last 30 seconds. Drained and served. I could have served them with the broth, but wasn't in a soup mood.
