My current favorite salad dressing is rather simple :-)
I use equal amounts of Extra Virgin Olive Oil and Balsamic Vinegar and mix throughly.
I usually put in a re-used jar or small olive oil jar with the pouring spout to making storing and pouring easier. After pouring a small amount on my salad I usually top with some celtic sea salt!
