Preheat oven to 400. Place won ton wrappers in miniature muffin cups and press the pastry to fit the shape of the cup. Place them in the oven and bake 6 minutes, or until golden brown and crisp. Meanwhile, cut chicken into small dice. Heat oil in large frying pan. Add chicken and cook, stirring occasionally, until it begins to brown, about 5 minutes. Stir in salsa and cook until heated through, about 1 minute. When pastry cups are done, remove from oven and fill with chicken. Garnish with cilantro.
