Put the spaghetti in plenty of boiling salted water and cook according to the instructions on the packet.
During this time, heat the olive oil in a pan and lightly brown the pine nuts in it.
If you like it spicier, you can add a fresh, chopped chilli pepper here. Add the garlic in fine slices, but do not brown.
The spaghetti should now be ready to cook and drained. Put the tomatoes in halves in the pan and let them soften only slightly. Season with salt and pepper.
Now add the spaghetti and mozzarella to the pan. Swirl everything gently until the mozzarella pulls strings and is melted. Add the rocket and stir again.
Wonderfully light and summery and yet very strong in taste.
