For the topping
Dissolve the yeast in warm water. Add the flour, a pinch of salt and knead the dough until it is smooth and elastic. Roll out the dough with a rolling pin, place it on a greased baking sheet and leave it to rise for about 40 minutes, covered with a clean tea towel.
In the meantime, drain the canned whole peeled tomatoes in a colander, pressing down gently to remove any excess juice, and then roughly chop them.
Roll out the dough evenly and place it on a greased baking sheet or pizza pan. Spread the chopped tomato evenly over the dough, leaving a border of about 2 cm. Sprinkle over the thinly sliced garlic cloves and the dried oregano. Drizzle generously with the olive oil. Season with salt and freshly ground black pepper.
