In a large bowl, combine all ingredients and carefully toss until fully incorporated.
Serve with chips, chicken or fish.
Notes
Try to dice the mangoes into small even pieces for easier eating with chips and incorporation with the other ingredients. Keep all of the ingredients roughly the same size.
Make ahead up to 24 hours - It's even better the next day.
Store leftover salsa in an airtight container in the fridge and it will keep fresh for up to 4 days, but it will become juicier as it sits. Drain extra liquid or serve with a slotted spoon.
