You could do Thai fishcakes with the addition of red curry paste, fish sauce, etc.
I once made some fishcakes adding in some leftover frozen peas, slightly crushed with a fork - I wouldn't say it jazzed them up, but they were quite nice.
Fantastic stuff. I've just made some plain ones...rolled in my own breadcrumbs and my daughter is tucking into them so they must be ok.
This is my first try at fishcakes. The remaining 6 cakes will have various ingredients added and i shall cook them so they're ready when my good lady wife returns from work at 9.30
