Start by removing the pineapple fruit from the skin, and set aside.
If you want it to look like the picture, cut the pineapple in rings and set aside, otherwise, cut into chunks and use in the next step.
Next, combine all of the rest of the ingredients in a large bowl and mix well.
Spoon the combination of fruit into the empty pineapple and top with additional lime juice, salt, and chili powder.
Decorate with the pineapple rings and serve!
