In a blender, combine the sliced strawberries and lime juice. Blend until smooth. If you prefer a chunkier texture, pulse a few times instead of blending completely.

In a large glass or pitcher, mix the Sprite with the vodka (if using).

Add the strawberry puree to the Sprite mixture and stir gently to combine.

Fill glasses with ice cubes and pour the strawberry dirty sprite over the ice.

Garnish each drink with fresh mint leaves and a few extra strawberry slices if desired.
