Chicken skewers get a little French makeover with grilled leeks (yum!) and grilled potatoes ( double yum!) all lathered up in a Dijon Garlic Rosemary Sauce. Serve this with a Caesar salad, and enjoy a healthy light and flavorful dinner!

This recipe was inspired Maille, a French gourmet mustard company who challenged me to come up with a new recipe using one of their products. Well, this was easy because I use their mustard all the time…. in dressings, marinades and sauces. It’s my mustard of choice in this Mustard Crusted Salmon Recipe.


La Maison Maille has been producing French style mustards, vinegar, olive oil and cornichons for more than 250 years. Recently it opened its first boutique store in New York’s Upper West Side and launched an online store that ships its gourmet products around the world.



In this recipe, leeks are sliced and blanched for just a few moments. Potatoes are blanched until tender, about 15 minutes. If you’ve never tried grilled leeks, you are in for a treat. Brian actually got me hooked on these last summer. He would grill whole leeks, low and slow on the grill and serve as a side with crumbled goat cheese….so tasty!

So it was he who gave me the idea of putting them on the skewer. The first time I made these, I did not blanch them first. The leeks were underdone. The quick blanching makes them easier to skewer, gives them a bright green vibrancy, and allows them to grill to perfection. So be sure to blanch first!

Dijon mustard, olive oil, garlic, rosemary and salt and pepper are mixed up in a small bowl. The marinade will seem especially strong, so don’t let it startle you. It mellows out perfectly once grilled.
