Not sure if this is the type of dressing you are looking for, but I bet it wold be good over the salad you described..... Theother possibility is to use some Pina Colada concentrate (in the frozen juice concentrate section) and add it to a basic vinaigrette recipe.

Good luck I hope you find what you are looking for it sounds really tasty!

"Perk up an ordinary salad with this tangy mixture shared by Shawn Nelson of Evansville, Indiana. With sweetness from pineapple juice and a but of zip from cumin, her salad dressing is a refreshing change of pace."
Ingredients:
1/2 cup unsweetened pineapple juice
1/4 cup white vinegar
1 teaspoon ground cumin 1 garlic clove, minced
mixed salad greens

Directions:
1. In a jar with a tight-fitting lid, combine the pineapple juice, vinegar, cumin and garlic; shake well. Serve with salad greens. Refrigerate leftovers; shake or stir before serving.

This is similar to what you had. It sounds delicious.
