Avocado, Tomato & Fresh Mozzarella Toast

One of my very favorite foods is avocado toast. I never seem to get it quite to my liking at home, mostly because of the bread. It takes a fresh, hearty, crusty bread that toasts up nicely and I just never seem to have the right kind. 

When I do have some suitable bread on hand, I usually add a little tomato, freshly ground pepper and some garlic salt. I recently had some in a restaurant with some fresh mozzarella on it and I loved that addition. My sister also made some for me with brie, which I also loved. Are you a fan of avocado toast? What other toppings do you add to yours?
