Grilled Sweet Potato and Red Pepper Salad Recipe

For dressing, in a small bowl, whisk the first seven ingredients; set aside. Using long-handled tongs, moisten a paper towel with cooking oil and lightly coat the grill rack. Grill red peppers over medium heat for 10-15 minutes or until the skins blister, turning frequently. Immediately place peppers in a large bowl; cover and let stand for 15 minutes. Meanwhile, in a shallow bowl, drizzle sweet potato slices with 2 tablespoons dressing; toss to coat. Set remaining dressing aside. Arrange potato slices on a grilling grid; place on a grill rack. Grill, covered, over medium heat for 5-6 minutes on each side or until tender. Cut into bite-size pieces. Peel off and discard charred skin from peppers; seed and coarsely chop. In a large bowl, combine the potatoes, peppers, celery, onions and cilantro. Whisk the reserved dressing; pour over salad and toss to coat. Serve at room temperature.
