Remove the skin from a pineapple. Cut into quarters and remove the core. Take one-quarter piece of pineapple and cook on a grill or grill pan over medium-high heat, about 3 minutes per side, or until grill marks are visible. Remove from the grill and allow to cool. Once cooled cut into a small dice and add to a mixing bowl.
Cut the bell pepper, red onion, and tomato into the same size. Mince the cilantro and add all the ingredients to the bowl.
