"With salad and a glass of good wine, this savory tart creates the perfect meal," says blogger Mimi Thorisson of this hearty dish. Made with caramelized onions tossed in a honey and balsamic vinegar glaze, it has just a hint of sweetness. She recommends using a base of classic yellow onions, while a ready-made puff pastry keeps the preparation utterly painless.
