Vietnamese Pork Meatballs Soup with Winter Melon (Canh Mọc Nấu Bí Đao)

Here is quick pork meatball soup recipe that I made with winter melon (bi dao). Winter melon is part of the gourd family. The outside usually has light green specks on them and some varieties have a bit of fuzz on the skin. Winter melon has the texture of a cucumber that cooks up quickly and provides sweetness to soups. Winter melon with tender pork meatballs is a must-have soup for these cold winter days.
