Prepare your pineapple. Skin and core your pineapple, then dice it into small pieces. Add this to your mixing bowl.
Juice your lime and add the juice to the bowl.
Remove seeds from your jalapeno and mince into small pieces. Add to the bowl.
Mince your onion, then add it to the bowl.
Pick the leaves off of your cilantro; do not leave any thick stems. Chop this and add it to the bowl. I used about a 1/4 of a bunch from the grocery store.
Remove the seeds and ribs from a red pepper. Mince half of the red pepper to about the same size as your onion. Add it to the bowl.
Add the salt and mix well. Chill for at least an hour for the best flavor.
