Quick Tip

Using mustard instead of mayonnaise on your sandwich is an easy way to boost flavor and nutrition while keeping fat to a minimum. Mustard even contains protein and is low in calories.

The Romans most likely developed the prepared mustards we know today. They mixed unfermented grape juice, known as "must," with ground seeds (called sinapis) to form mustum ardens, or "burning must."

So, do as the Romans do and eat your mustard!
