In a large mixing bowl, add the pineapple, cucumber, red onion, cilantro, jalapeño, and garlic. Drizzle in the fresh lime juice and season with a dash of salt and pepper.
Using a spoon or spatula, mix everything together thoroughly until well combined. Ensure the ingredients are evenly distributed for balanced flavor in every bite.
Cover and chill in the refrigerator before serving. Enjoy cold as a refreshing side, dip, or topping for grilled proteins.
