½ ripe pineapple, peeled and sliced lengthwise into ¼" slices
½ small red onion, minced (about ¼ cup)
1 jalapeño pepper, seeded and minced
½ red bell pepper, seeded and diced
juice and zest of ½ large lime (about 1 Tbsp), or more to taste
2 Tbsp rice vinegar
1 Tbsp minced fresh cilantro
1-2 Tbsp olive oil
Kosher salt and freshly ground pepper, to taste
Preheat grill for direct grilling on medium-high heat. Carefully oil the grill grates (tongs and oil-soaked paper towels do a good job of this).
Place pineapple slices on the grill. Grill for about 2 to 3 minutes per side, turning once during grilling.
Transfer slices to a cutting board and dice into ¼" cubes. Place diced pineapple in a large mixing bowl, and add all remaining ingredients. Season to taste with salt, pepper, and additional lime juice if necessary.
