Preheat the oven to 375 degrees.
In a small bowl, whisk together the vinegar, mustard, honey, 1 teaspoon salt, and ½ teaspoon pepper. While whisking, slowly add the olive oil. Set aside.
Remove the stems from the figs with a small knife. Depending on their sizes, cut the figs in half or quarters through the stem end. Place the figs and walnuts together in a single layer on a sheet pan and roast for 5 to 15 minutes, depending on the ripeness of the figs, until they begin to release some of their juices.
Meanwhile, place the arugula in a large bowl, add the vinaigrette, and toss well. Distribute the arugula among 6 salad plates, add the Roquefort, and then place the warm figs and walnuts on top. Serve immediately.
