I've said it before, but some of my all-time favorite recipes come from Southern Living magazine, particularly their summer issues.  This is another favorite that I tweaked the instructions for just slightly, but overall kept the ingredients pretty much the same.  The simple balsamic and olive oil penne pasta base is so light, flavorful, and perfect for summer.  It also allows the dish to be able to be served both hot or cold, and makes it compatible with a variety of different ingredients if you want to switch it up!  This is a great "clean out your fridge" pasta as you can customize it as you want with any kind of cold cuts, Italian cheese, and roasted vegetables.
