If Italians made nachos, this is what I imagine they would be like...
Italian toasts or panetini (Nonni brand is very good)
Bruschetta topping (or a homemade concoction of diced tomatoes, dried basil, garlic salt, and olive oil)
Red onion, chopped
Mushrooms, chopped and sauteed
Kalamata olives, chopped
Fresh (Buffalo) mozzarella, roughly chopped
Parmesan cheese, freshly grated
Salt & pepper, to taste
Extra virgin olive oil (optional)
Layer all ingredients in a pan (I used a small non-stick sheet pan). Start with the toasts and layer all the ingredients--dropping bruschetta topping and pesto onto the ingredients and ending with cheese(s). Feel free to season and drizzle with olive oil.
Broil (on low if you can) or roast until the cheese melts and starts to slightly brown.
Makes a really good appetizer. I hope you like it.
