Brew the black tea according to package instructions and allow it to cool completely.

In a large pitcher, combine the cooled tea, mango juice, diced mango, honey, and lime juice. Stir well until the honey is fully dissolved.

Taste the mixture and adjust sweetness by adding more honey if desired.

Fill glasses with ice cubes and pour the mango iced tea over the ice.

Garnish with fresh mint leaves if desired and serve immediately.
