Avocado Parmigiano Sandwich

This morning, while making my breakfast sandwich, I was singing "pa pa pa pa parmigiano re re re re reggiano" , because it included finely grated Parmigiano Reggiano cheese, along with avocados and tomatoes, on toasted multigrain rye bread with mayo spread.

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.
