Preheat your oven to 375°F (190°C). Arrange the baguette slices on a baking sheet. Toast in the preheated oven until slightly golden and crisp, about 5-8 minutes. Watch carefully as they can burn quickly due to their thinness.
Allow breads to cool for a few moments before spreading your chosen tapenade or tomato sauce on each slice. Garnish with chopped fresh parsley just before serving.
