Preheat the oven to 450°F (230°C). Make sure the baking sheet or pizza stone is warming up in the oven.
Add the dry yeast to the warm water and stir to dissolve.
Add the flour and salt to a mixing bowl.
Slowly add the water, the extra-virgin olive oil, and mix for 5 minutes. If your dough is a bit too wet, add a bit more flour, but make sure you don’t add too much or the pizza will be hard. After kneading, the dough should be smooth and elastic.
Shape the dough into a ball and place in a large mixing bowl at least twice the size of the dough, coated with extra-virgin olive oil. Cover with plastic wrap and leave it to rise in a warm location for at least 45 minutes (if you can leave it longer, it won’t do it any harm).
Turn the dough onto a floured surface, divide it into 2 balls and using a rolling pin to roll the dough into two 11 inches rounds. Don’t worry if the shape isn’t perfect, but make sure the pizza crust is thin and of consistent thickness all around.
Make sure the oven is really hot. Remove the hot baking sheet or pizza stone and transfer the pizza dough on it.
Top with tomato sauce, mozzarella, olives, capers, and chili or any other toppings you like.
Put back in the oven and bake for 10-12 minutes, or until the crust is golden brown and the mozzarella is melted and cooked. If you are using a pizza stone, your pizza will cook much faster: make sure you allow only 6-8 minutes.
Add the rocket, slice and serve warm.
