"Greek" sandwiches

Today's breakfast sandwich had a definite Greek theme. All traditional Hellenic ingredients, like Feta cheese, black olives, tomatoes and red onions, were present in it. Plus, an avocado, which is more Mexican than Greek.

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.
