Preheat oven to 220°C fan-forced. Line an ovenproof dish with a 20cm square of baking paper. Place brie in the centre.
Combine the tomatoes, oil, thyme, garlic and chili flakes in a large bowl, season. Spoon over the brie and bake for 10-12 minutes, or until cheese is hot and tomatoes start to split. Remove from the oven and drizzle with caramelized balsamic.
Arrange prosciutto, olives, crispbread, crackers and figs on a large board. Scatter with micro herbs. Serve with warm brie.
