IF SERVING NOW - Prepare the crostini toasts:
Lay out the Italian bread slices on a cookie sheet. Lightly brush each bread with olive oil. The new silicone brushes are great. They wash up really easy.
Put the cookie sheet under broil. Don't do anything else. Just stand there and keep checking the bread and don't let burn. It only takes a couple of minutes.
After the toasts are lightly browned, remove from the oven. They are ready to use anytime.
Spread with Balsamic Caramelized Onion or serve Balsamic Caramelized Onion in a bowl with the toasted crostini on the side.
You can keep the toasts in the refrigerator for later use too. Like, if the party is tomorrow or in a few days.
