Cook the spaghetti according to the instructions on the packet.
Put the olive oil in a large pan and let it get hot. Wash the cherry tomatoes, quarter them and add them. Peel and squeeze the garlic. Crumble in the chilli pods (a fresh pod can be used instead of dried chillies). Simmer long enough for the garlic to be nicely roasted. Drain the finished spaghetti in a colander, add to the pan and mix everything.
Clean the rocket, chop it up a little and divide about half of the pack on two plates. Then place the spaghetti on top and serve sprinkled with parmesan.
