Pick the leaves off the sprig of mint and place in a small mug, along with the green tea bag. Boil some water, and allow it to cool to approx. 80 degrees C. Infuse the mint and green tea for 2-3 mins, and then stir in the honey.
Meanwhile, fill a glass with ice, and an optional small sprig of mint for garnish. Strain the infused tea, and pour straight into the glass, and serve right away.
