1. In a medium bowl whisk together garlic, lemon juice, salt, pepper, mint leaves and olive oil for 2 - 3 minutes. Set aside.
2. Gently add the feta and olives in the jar with the lid.
3. Pour the marinade in the same jar. Close with the lid. Gently shake and keep in the fridge for atleast 1 - 2 hours. Or keep in the fridge until ready to serve.
4. It is recommended to prepare the marinade in a large jar so that it's easy to coat the cheese and olives with the marinade.
5. To make the skewers, place an olive, then a chunk of cucumber. Gently place a cube of the marinated feta followed by a black olive.

Enjoy your meal!
