Preheat oven to 200°C fan forced. Combine all the dressing ingredients in a screw top jar, season and shake until well combined.
If preferred, halve the tomatoes. Arrange tomatoes in a roasting pan. Drizzle with half the olive oil, season. Allow to roast for 5-7 minutes until softened slightly. Pour the dressing over the warm tomatoes and set aside for 30 minutes to marinate.
Meanwhile, brush the baguette slices with remaining oil, place in a single layer on a baking tray and bake for 5 minutes or until golden. Set aside to cool for 10 minutes.
Arrange baguette over base of a serving platter or board. Scatter over the parsley leaves. Spoon over the tomatoes, top with feta, capers and olives. Pour over any dressing from the tomatoes. Season and serve.
