Add all ingredients to a large bowl, stir to combine, taste, and make flavor adjustments as necessary.
After peeling and trimming the flesh of the mango away from the seed, squeeze the seed tightly over the mixing bowl to collect extra mango juice which adds extra mango flavor to the salsa.
Serve immediately with chips or your favorite dippers, or transfer to an airtight container and refrigerate for up to 24 hours before serving. The flavors marry over time and the salsa tastes even better on the second day.
Notes
Storage: Salsa will keep airtight in the fridge for up to 4 days, noting that the fruit will release juices as time passes.
