Dessert Skewers

Place brown sugar, lime juice, vanilla and salt in a small saucepan. Whisk the mixture over medium heat until it boils. Continue stirring until sugar is completely dissolved. Remove from heat and allow to cool in a shallow pan. Core pineapple and cut into 8-10 long pieces; thread on skewers. Coat pineapple pieces with some of the sauce. Grill over medium-high heat until all sides are golden-brown, about 4 to 5 minutes per side. Serve with any remaining sauce.
