Cut the pineapple down the center lengthwise so the stem is also cut down the center. Do this carefully so the stems stay attached to each half.
Cut a grid pattern of squares into each pineapple half making sure not to cut through the rind. I left about an inch of pineapple around the edge of the rind. Dig out the pineapple chunks and chop them into very small chunks. Put them into a large bowl.
Chop the tomatoes, onion, orange pepper, and jalapeno pepper into small pieces. Put those in the bowl with the pineapple.
Chop a small bunch of cilantro and put that in the bowl along with the salt and the cumin.
Gently mix everything together and squeeze the juice of one or both the limes over the salsa and mix again.
Add salsa to the hollowed-out pineapple halves, then serve with tortilla chips.
Notes
Uniform chopping makes the salsa look beautiful and ensures balanced bites.
For less heat, remove the jalapeno seeds before chopping.
Taste and adjust lime juice and salt right before serving for maximum freshness.
