Caramelized Sweet Onions & Bacon Tart

An easy and flavorful onion tart recipe given to me some years ago by my mother. I'm not sure where it originated. Even my picky husband likes it. Feel free to experiment and tweak it with your favorite seasonings. Sometimes I add mushrooms, too, just because I like them.
