For the chicken cigars: Preheat oven to 425 degrees F.
Place chicken in a bowl and mix with spices and parsley. Place a piece of phyllo on a nonstick cookie sheet and brush with some of the melted butter. Repeat 3 more times, placing each piece of phyllo over the last buttered sheet to make 4 layers. Cut phyllo into 2-inch squares. On 1 corner of each of the squares, place about 1 1/2 teaspoons of chicken filling. Roll up tightly to make mini "cigars." Place "cigars" on a sheet pan and butter the tops of each. Bake for 10 to 15 minutes, until golden brown.
Meanwhile, make the sweet and sour mango dipping sauce: Whisk together plum or duck sauce and vinegar in a bowl. Stream in oil and continue whisking to combine. Season with salt and pepper. Fold in mango and sliced scallions.
Serve cigars with dipping sauce.
