In 10-inch skillet, heat 3 tablespoons of the oil over medium heat. Add 3/4 cup onions; cook 2 to 3 minutes, stirring frequently, or until onions are softened. Add chicken, curry powder, garlic powder, and 1/4 teaspoon of the cayenne pepper; cook 2 minutes, stirring constantly. Stir in pineapple juice, crushed pineapple, raisins, coconut and pickles. Bring to a boil. Reduce heat to medium-low; simmer uncovered 7 to 10 minutes, stirring occasionally, or until liquid is absorbed. Remove from heat.
