Chop tomatoes, chilli peppers and garlic and sauté them together in a small saucepan in olive oil. Deglaze with a little wine, let it boil down and deglaze with the rest of the wine.
At the same time, cook the spaghettini al dente. Wash the rocket, pat dry and cut into bite-sized pieces. Thaw the prawns and fry them in the olive oil.
Drain the spaghettini, place in a large bowl with the prawns and rocket and pour the sauce over them. Mix everything together and serve immediately.
