Peel and slice the banana and freeze it for at least 2 hours.
Peel and cut a mango into small pieces.
Add frozen sliced banana, mango and Agave into a food processor. Taste your mango first, if it's sweet already you may just need 1 tablespoon of Agave.
Chop everything together until you get the soft ice cream consistency.
You can eat it right away but it will be pretty soft. Put it in a container and freeze it until it's solid like ice cream.
Notes
I used 2 tablespoons of Agave, you can use more or less depends on how sweet your mango is.
