In a small bowl, combine the mayo, sour cream, and curry. Mix well.
In a large bowl combine the chicken and drained pineapple. Stir in the curry mayonnaise and mix well. Then stir in the mango chutney, stirring until well blended. If you want to add in the coconut and/or pecans, stir them in now. If the salad is too dry, make another batch of the curry mayonnaise and toss it in. Chill for at least 30 minutes before serving.
Make sandwiches with the croissants, lettuce, and chicken salad.
