Caramelized Onion Tart

I pulled all the remaining onions from the garden yesterday.

OnionsToday, I cleaned them, peeled the skins and chopped them for freezing. I kept three large onions to make a caramelized onion tart. There is such satisfaction in pulling something from the ground and cooking it within a few hours.
