Halve the flatbread crosswise. Place both halves on baking sheets and drizzle with olive oil. Sprinkle with garlic and herbs of Provence. Cover with the tomato slices and season with salt and pepper. Spread the spring onions and finally the mozzarella on the bread and sprinkle lightly with salt and pepper again. Drizzle again with a little olive oil.
Bake in a hot oven at 200 ° C for about 15-20 minutes until the mozzarella has melted nicely. Sprinkle with basil leaves and drizzle some crema di balsamic vinegar over them.
