BROILED TOMATO SANDWICH

1. Combine Ingredients: In a small saucepan, combine the balsamic vinegar and brown sugar over medium-low heat.
2. Simmer: Bring the mixture to a low boil, then reduce the heat and simmer for 8-10 minutes. The reduction should thicken and be able to coat the back of a spoon.
3. Cool: Remove from heat and let it cool. The glaze will continue to thicken as it cools.

Preparing the Bread and Toppings

1. Mix Olive Oil and Spices: In a small bowl, combine the olive oil, garlic powder, onion powder, dried oregano, dried marjoram, and ground thyme.
2. Toast the Bread: Lay the Italian bread slices on a large baking sheet. Brush the tops with the olive oil mixture. Toast under the broiler until lightly browned. Stay close and monitor as broilers can work quickly.

Assembling the Sandwich

1. First Cheese Layer: Sprinkle about half of the shredded mozzarella evenly over the six slices of toasted bread.
2. Add Tomatoes: Arrange the tomato slices on top of the mozzarella layer. Brush the tomatoes with any remaining olive oil mixture.
3. Second Cheese Layer: Top the tomatoes with the remaining shredded mozzarella and Parmesan cheese.
4. Broil: Place the sandwiches under the broiler for 2-3 minutes, checking every minute and rotating the baking sheet for even cooking. Broil until the cheese is melted and lightly browned.

Finishing Touches

1. Drizzle with Balsamic Reduction: Once the sandwiches are out of the oven, drizzle them with the prepared balsamic reduction.
2. Garnish: Top with fresh basil and parsley for a burst of freshness.
3. Serve Promptly: For the best taste and texture, serve the sandwiches immediately.
