Pour over Pimms and lemonade (important: please see Note 1). Stir to combine.
Add cucumber, strawberries and mint to the pitcher.
Divide between four glasses and serve.
Note 1: Use Sprite/7-Up or other similar sweet sparkling drink for this recipe, not the flat sugary-lemon drink often referred to as lemonade in North America. In New Zealand, Australia and UK we refer to Sprite/7-Up etc. as "lemonade".
