In a large bowl, combine the chopped rotisserie chicken, thoroughly drained crushed pineapple, honey-roasted almonds, thinly sliced celery, and finely diced red onion. Stir to mix evenly.
In a small bowl, whisk together the mayonnaise, sour cream, honey, Dijon-style mustard, lemon juice, and a generous pinch of salt and pepper (about 1/4 tsp salt and 1/8 tsp pepper, or to taste).
Pour the dressing over the chicken mixture and gently fold until everything is evenly coated. Taste and adjust seasoning with additional salt, pepper, or lemon juice as needed.
Serve the chicken salad on croissants or your choice of bread or rolls, adding lettuce if desired. Enjoy immediately.
