Top the brie pieces with the jarlsberg and lightly press together to have them stick to one another. Place an olive half on top of each of the combined cheeses.

Pierce a basil leaf with a toothpick and then pierce through the olive and cheese. Place a tomato half on top, cut side up, and piece the toothpick through. Transfer to a serving plate and repeat with the remaining portions.

Drizzle the prepared items with olive oil and balsamic vinegar. Season with salt and pepper and serve immediately.
