Swiss chard is delicious when it is prepared properly. If not prepared properly it can be soggy and unpalatable. This is a super easy way to have success every time. Use this recipe for any braising greens: kale, collards, beet greens, etc.
Whisk the sour cream, vinegar, sugar, dill, and salt + pepper to taste in a medium bowl. Add the cucumber, kohlrabi, baby kale, and scallions and mix to coat with dressing.
