How to Make It
In a small bowl, whisk together the maple syrup, mustard, vinegar, salt, and pepper. Whisking constantly, slowly add the oil; set aside.
Arrange the arugula on individual plates and top with the pear and cheese. Drizzle with the vinaigrette.
Tip: For a warm salad, heat the vinaigrette in a small saucepan over medium heat for 1 minute, and substitute spinach for the arugula.
