To make this crunchy schiacciata, start by mixing the flour with the water and 2 teaspoons of salt in a bowl using a whisk.
Then cut the cherry tomatoes in 2 and add them to the mixture. Mix everything together. Oil and flour a 30 cm baking dish, then sprinkle with cornflour.
Pour the mixture into the baking dish, level it and then sprinkle it with more cornflour. Add a few slices of red onion, a pinch of oregano and top with a generous drizzle of oil.
Bake at 200°C (392°F) for 50 minutes and at 230°C (446°F) for 10 minutes.
Finally, take out of the oven, cut into wedges and enjoy the crunch. Enjoy your meal!!
