There are many people out there who falsely believe that Italian food is all about mountains of red sauce and meatballs. This is not the case at all. In fact, eating like an Italian is far different than you would probably think (take it from someone who have been to many Miami Italian Restaurants).
One thing you should know is the fact that tons of sauce is not an Italian thing. The idea is to coat your pasta with a small amount of sauce and allow it to coat the noodles. This is a far cry from the marinara bathed pasta most people associate with Italians.
You must have good olive oil if you want to eat like Italians. This is a staple in all Italian households. If you are not a fan of olive oil then there is really no way to have a truly authentic Italian eating experience.
Another thing you should never forget is good wine (Best Italian Restaurants in Miami have these wines). This is important for adding to recipes as well as drinking on the side. As long as you have good wine, you will do fine when it comes to being authentically Italian.
This may seem simple, but that is exactly how eating is in Italy. Simple ingredients that are delicious in their own respect.
