Steps:
- Thaw the pastry sheet at room temperature for 40 minutes or until it's easy to handle. Heat the oven to 400 degrees F. Line a baking sheet with parchment paper or spray with vegetable cooking spray.
- Heat the oil in a 12-inch skillet over medium heat. Add the onion and cook for about 15 minutes or until golden, stirring often. Season to taste and let cool.
- Unfold the pastry sheet on a lightly floured surface. Roll into a 12-inch square. Place on the prepared baking sheet. Brush the edges of the square with water. Fold over the edges 1/2 inch on all sides, pressing firmly with a fork to form a rim. Prick the pastry thoroughly with a fork.
- Spread the onion mixture over the pastry crust. Top with the gruyere and parmesan cheeses and sprinkle with the chives.
- Bake for 20 minutes or until golden and bubbly. Cool for 5 minutes on a wire rack. Cut into approximately 3 x 2-inch rectangles. Serve warm.
