Arugula and bacon quiche

I took this to a potluck. My attempt was not as outstanding as the reviews on epicurious had led me to believe. I've had a year long love affair with arugula, particularly when matched with bacon, but this didn't quite do it for me. I will make it or a similar recipe again, but I'll want to moderate the bacon more carefully (I over indulged in my version). When combined with the Gruyere, there's was a bit too much grease for my taste. The addition of balsamic vinegar to the sauteed arugula was inspired, however, so I'll steal that little bit of cooking wisdom for later use.
