Start by prepping all your vegetables and the fruit. If you want a spicy salsa, leave the seeds in the jalapenos. Otherwise, cut pepper lengthwise and scrape out all the seeds and white vein. Rinse in water, then mince.
Add all the ingredients into a bowl, toss and then season with salt to taste if you would like.
Serve this mango salsa with tortilla chips, chicken, fish, or other Mexican dishes.
You can use a Serrano pepper in replace of the Jalapeno if you want. Or for a very mild option use a green bell pepper. You can use frozen mango in replace, but it will alter the texture of the salsa. This salsa will store in the fridge for a few days. Just toss and then serve like fresh.
