For the mozzarella baguettes, first preheat the oven to 200 degrees and line a baking sheet with baking paper. Wash the tomatoes and cut them into thin slices. Remove the mozzarella from the package, dab it a bit and cut it into thin slices as well.
Take the baguettes out of the package and make a wide (but not too deep) cut every 2-3cm. Now fill these cuts alternately with one slice each of tomato and mozzarella.
Drizzle the filled breads with a little olive oil and sprinkle with herbs. Season lightly with salt. Bake for about 15 minutes, until the cheese is well melted and the breads are nicely browned.
Arrange the mozzarella baguettes and serve.
