We got a bunch of cippoillini onions from our crop share this year and couldn't figure out what to do with them. I came across this recipe for a rustic tart and was thrilled. Not only did it use all of the cippollini onions but it was super delicious and very pretty. The onions melt in your mouth and the tart has an amazing savory flavor. I would definatly serve this at a dinner party. I think this would work nicely as single serving mini tarts as well.
