  2. Heat olive oil in a large, heavy-bottomed sauté pan on medium heat. Add the onions and sprinkle a little salt over them. Cook, stirring occasionally for 10 minutes, until the onions have softened and are translucent. Reduce the heat to medium-low and cook for an additional 40 minutes, stirring occasionally, until the onions are well browned. Add balsamic vinegar and cook for 10 minutes more, until onions are completely caramelized. Remove from heat.
  3. Place tart pan on a baking sheet to catch any run-off there might be. Sprinkle half the cheese evenly over the bottom of the crust. Spread onions over the cheese and then top with remaining cheese. In a medium bowl, whisk together milk,
