Kielbasa and Lentil Salad with Warm Mustard Fennel Dressing

Why I Love This Recipe
*FENNEL BULB WITH FRONDS - Fronds are deeply dissected simple leaves that resemble ferns. The leaf includes the whole frilly structure right to where it intersects the stem. It has bright green feathery fronds that resemble dill. The fronds can be used as a seasoning, eaten alone or in salads, or even used to make a tea.
**FRISÉE [free-ZAY] - A member of the chicory family, frisée has delicately slender, curly leaves that range in color from yellow-white to yellow-green. This feathery vegetable has a mildly bitter flavor and is often used in the special salad mix, mesclun. Choose frisée with crisp leaves and no sign of wilting. Refrigerate in a plastic bag for up to 5 days. Wash just before using.
