For a nutritious twist on wonton soup, add some bok choy to the mix. Bok choy is a leafy green vegetable that is packed with vitamins and minerals. In this recipe, the bok choy is added to the broth along with the wontons, allowing it to cook until tender. The result is a soup that is not only delicious but also incredibly healthy. The bok choy adds a refreshing crunch and a slightly bitter taste that complements the savory wontons perfectly.
