This bruschetta has a great garlic-tomato flavor with a zing of balsamic vinegar in the mix. I settled on this ratio of ingredients after trial and error with a few other recipes. This is a really great appetizer to make ahead, which makes the flavors much more intense. (Then you just have to toast the bread.) I give instructions on blanching the tomatoes to remove the skin, but if you're short on time you can just dice them.
