Gather all your ingredients for Pineapple Pico de Gallo. Chop the pineapple into small cubes, dice the red onion, finely chop the jalapeno, chop the red bell pepper, and roughly chop the cilantro.

In a mixing bowl, combine the diced pineapple, red onion, jalapeno, red bell pepper, and chopped cilantro. Gently fold the ingredients together using a spatula.

Squeeze the juice of a lime over the mixture and add salt and black pepper to taste. Mix well to integrate the flavors.

Stir the mixture again, taste, and adjust seasoning if necessary for balance.

Optionally, sprinkle Tajin over your Pico de Gallo and gently fold it in.

Serve immediately with tortilla chips or as a topping for tacos.
