*You could substitute any affordable tomato for the slicer tomatoes I used. Roma is often less expensive, but the slicer tomatoes looked better when I was at the store, so that's what I went for! I don't recommend canned tomatoes, as the texture is too soft.**Don't skip the fresh basil, as it provides the defining flavor of this recipe. It does up the price quite a bit, but the flavor cannot be replicated with dry herbs. It's worth the splurge!***Optional: Whip up a quick batch of our homemade balsamic glaze for drizzling over each portion. It takes this appetizer to the next level!
