Grilled Mustard Chicken with Creamy Walnut Sauce

So back to this mustard chicken. You guys, where do I even begin? It's tender, flavorful, extremely simple to make and it's drizzled with a 5-minute, dairy-free mustard cream sauce. It's rubbed with Maille's walnut and white wine mustard that, if you haven't tried it yet I'd suggest getting yourself a bottle asap. It has a nutty and earthy flavor with a tiny touch of sweetness. It reminds me a little of black garlic. I wanted to keep things simple with this recipe to really highlight the flavor of this very special mustard. It's very strong and assertive and bold-flavored dreamy.

→ sidebar ← Before my box of 5 gourmet mustards arrived in the mail, I genuinely did not think that flavored mustards would be all that different from each other. You know, like you could easily substitute one for another. I was wrong! Very, very wrong. Each of the five mustards I was given has a totally unique flavor. I'm about 100% sure that I'm now going to have to spend all the money I'm making from this post just to buy the remaining 29 other flavors. 

My two favorites are the walnut mustard and Maille's extra special on-tap white wine mustard. Maille has a line of 5 on-tap mustards that are poured into earthenware pots and sealed with cork stoppers. The on-tap white wine mustard that I got was extra creamy and very strong. It's unmistakably Dijon, but about 100x better than any I've ever tried before. I was tempted to eat the whole bottle, one tiny little spoonful at a time, but came to my senses just before the green beans went on the BBQ.

On-tap mustard + green beans + walnut mustard chicken = one awesome dinner.
