Preheat the oven to 375°F (190°C).
Arrange baguette slices on a baking sheet and lightly brush with olive oil.
Toast in the oven for 5-7 minutes until crisp and golden.
In a bowl, mix tomatoes, feta, olive oil, oregano, salt, and pepper.
Top each toasted baguette slice with the tomato-feta mixture.
Drizzle balsamic glaze over the bruschetta before serving.
