- 1/4 cup balsamic vinegar
- 3 tablespoons brown sugar

- 1 package (17.3 ounces) frozen puff pastry, thawed

- In a large skillet, saute onions in 1/4 cup butter until softened. Add 3 bay leaves, 1 sage sprig and 1 thyme sprig. Reduce heat to medium-low; cook, stirring occasionally, for 30-40 minutes or until onions are deep golden brown. Add garlic; cook 2 minutes longer. Discard bay leaves, thyme and sage. Cool slightly.
