Brew the tea with boiling water, allowing it to infuse for 3 minutes before removing the tea bag. Place the tea in the fridge until completely cooled.
Put the cooled tea, watermelon, strawberries and lime juice in a blender and blitz until smooth. Add ice cubes and fresh mint leaves and use a pulse setting on the blender to crush.
Pour into glasses and drink immediately, garnished with lime rounds and extra mint sprigs.
