Set the grill to pre-heat.
Prepare the pineapple. Peel, core, and slice pineapple into 1/2" slices. To make a pineapple boat, see instructions below.
Brush oil on grates of grill and each side of pineapple slices.
Grill on low-medium heat 7 minutes, flip, and grill for an additional 7 minutes or until a nice char is achieved and pineapple begins to caramelize.
Once grilled, leave aside to cool completely.
While pineapple is cooling, prepare the rest of the salsa ingredients.
Add pineapple, peppers, tomatoes, red onion, corn, garlic, jalapeno and cilantro to a medium bowl.
Whisk together lime juice, honey, chili, cumin and garlic salt.
Pour dressing over chopped ingredients and toss well.
Cover and refrigerate 2 hours to chill.
Serve on side of grilled meat, salmon, or add to pineapple boat or bowl and serve with chips. Enjoy!
