This sweet-and-savory Brussels sprout slaw is the ultimate prep-ahead dish. In fact, we really recommend making it a day ahead, and not just because it’ll free up some time: A day of rest in the fridge results in more tender Brussels sprouts that are infused with flavor. Honey and Dijon mustard dressing sweetens and adds multi-dimensional character to these compact members of the cabbage family, creating a modern slaw that shines, especially when topped with savory bacon and toasty walnuts.
