Tuna n' Capellini

This is a real student type meal - quick, easy and cheap. I was first introduced to the concept when I moved into my first dorm some 11 years ago. There was a guy there who would eat this sort of meal several times a week; it was to be at least 3 years before I tried something along these lines for the first time, and I have to say I never did start eating it that often.
This time around it turned out like this.

Ingredients:
- 2 cans of tuna
- 1 onion
- 1 lb capellini (angel hair)
- oil, salt, (Madras) curry, tarragon

While the water for the pasta gets to a boil: In a pan fry coarsely chopped onion and tuna, season with salt, curry and tarragon.
