Hot-Smoked Trout Spagetti

Cook the pasta in plenty of gently boiling well-salted water until al dente.
Meanwhile  peel the garlic and chop it very finely. Also chop the spring onions.  Put the oil in a small pan and fry the spring onions and tomatoes, add  the garlic.
Drain the pasta and tip it into a warmed very large  serving bowl. Quickly add the lemon zest to the oil, then pour over the  pasta. Toss well, add the trout and toss again take care not to  break up the trout too much.
Sprinkle some Parmesan and serve.
