"Cucumber Caprese" sandwiches

Today's breakfast sandwich was a traditional Caprese, with sliced fresh mozzarella and tomatoes, but with cucumber replacing basil. Plus, I had used a more viscous balsamic reduction, instead of regular balsamic.

Here is a final result. Bon appétit! Hope to see you again. Also, would be very happy to receive your feedback or advice about my culinary creations.
