Combine the cabbage, carrots, apples, onion, and pecans in a large bowl. Mix well with your hands and set aside.
In a small bowl, stir together the mustard, sugar, mayonnaise, ground chipotle, and lemon juice until blended. Season with salt and pepper. Pour the dressing over the cabbage mixture and toss well to coat. Taste again for seasoning, then mound onto a platter and garnish with mint leaves.
