Heat the grill to medium-heat. Place the pineapple and onions onto the grill and let cook 1 to 2 minutes per side, or until light grill marks appear. Be careful not to burn it. Remove from the grill and allow to cool. Once cooled, chop into 1/4″ pieces and place in a medium-sized bowl.
Next stir in the bell pepper, cilantro and lime juice. Add salt and pepper to taste. For a little heat, add in jalapeno if you’d like.
Stir and then cover and refrigerate until ready to serve.
To add heat, mix in some chopped jalapeno.
For a fun twist, stir in 1 avocado cut into 1/2″ pieces.
Although I highly recommend grilling the pineapple/onions for extra flavor, you could skip this part if preferred.
