Peel the mangoes and remove the flesh from the pit, then dice into 1/4 inch cubes.

Wearing gloves to protect skin from oils, remove the seeds and membranes from the habanero peppers and mince finely.

Finely dice the red onion and chop the fresh cilantro.

Combine the mango, habanero, onion, and cilantro in a medium mixing bowl.

Add the lime juice, salt, and black pepper to the bowl.

Toss ingredients together gently until evenly distributed.

Refrigerate for at least 30 minutes before serving to allow the flavors to meld.
