In a medium bowl, add the diced pineapple, bell pepper, red onion, jalapeño, garlic, and cilantro. Pour in the lime juice and sprinkle the salt. Stir everything until well mixed.
Let the salsa sit at room temperature for about 10 minutes so the flavors meld. Adjust seasonings as needed. Garnish with extra cilantro; serve with tortilla chips if desired.
