Cut the pineapple lengthwise, with a knife cut the pineapple in chunks while leaving the outside intact to use the pineapple as the bowl. Spoon out the pineapple chunks.
Remove the woody pieces of the pineapple core and cut the rest of the pineapple in small chunks. Cube the cherry tomatoes and red bell pepper (remove the seeds). Chop the cilantro.
In a bowl, mix together the pineapple, cherry tomatoes, red bell pepper, cilantro and salt. Transfer it in the pineapple bowl before serving and enjoy! It's delicious with tortilla chips, for example!
