1. Preheat the oven to 375 degrees. While it's heating, lay the brie slices on the bread and place on a baking sheet. Bake for 8-10 minutes, until the edges are golden. Use a knife to spread the melty brie around a bit.
2. Meanwhile, stir together the tomatoes, truffle oil, basil, salt and pepper. Let sit while the bread cooks.
3. Once the bread is ready, plate the two slices and top with all the tomatoes.
