Finely chop the habanero pepper.

Chop the onion and pineapple.

Heat a little oil in a skillet and sauté the onion.

When the onion starts to change color, add the pineapple.

Sauté for about 3 minutes. When the pineapple softens, add the habanero pepper.

Cook for about 6 minutes, then season with salt, black pepper, and oregano to taste.

Cook for another 3 minutes, remove from heat, and let cool. Once cooled, add the apple cider vinegar and cilantro to taste.
