Preheat the oven to 400 degrees Fahrenheit. Arrange the baguette slices on a cookie sheet lined with parchment paper or a silicone baking mat.
½ baguette
Mix olive oil, balsamic reduction, Italian seasoning, and salt (if using) in a small cup. Using a basting brush, brush the mixture over the baguette slices.
2 tbsp olive oil, 2 tbsp balsamic reduction, 1 tsp Italian seasoning, 1 tsp salt
Top the baguette slices with diced dates, and then top with Gruyere and Swiss. Don't worry about shreds that fall off onto the baking sheet, they'll be a crunchy topping later!
6 dates, ½ cup Gruyere & Swiss
Bake for 7 minutes or until the cheese has melted. Remove from the oven and arrange on a serving tray. Crumble the crunchy cheese over top of the slices, and drizzle some extra balsamic reduction over top!
