To prepare crab mixture, combine first 13 ingredients in a medium bowl, stirring well with a whisk. Add crabmeat; toss gently to coat. Cover and chill until ready to use.
To prepare salsa, combine pineapple, mango, bell pepper, and chives; cover and chill until ready to use.
Preheat oven to 350°.
To prepare chips, spread 1 tablespoon cheese into a 3-inch circle on a baking sheet. Repeat procedure with remaining 1 tablespoon cheese, leaving at least 2 inches between circles. Bake at 350° for 8 minutes or until cheese begins to brown. Remove pan from oven; carefully lift chips from pan with a spatula, and place on a wire rack. Cool completely.
Spoon 1/2 cup crab mixture into each of 2 martini glasses or small bowls; top each serving with 2 tablespoons salsa and 1 chip. Serve immediately.
