Kohlrabi is another vegetable that is everywhere in Central Europe, and I quite like its flavor, though it is not very strong. It has a bit of a peppery flavor, so it goes well with mustard dressing.
Wash, peel and slice a kohlrabi into manageable pieces. Whip up a mustard dressing by mixing equal parts vinegar, oil, and grainy mustard with some salt and pepper. You can sweeten this with a bit of honey if you want, or just leave it as is, depending your mustard and your tastes. Toss kohlrabi with mustard dressing to coat and serve.
