Sometimes the simple approach is all that's needed.
Two decent sized haddock loins, two slices of wholemeal multigrain bread (toasted), and some melted butter. The toasted bread was blitzed in the blender. The butter was melted. the haddock dipped in the melted butter and rolled in the breadcrumbs. The remaining breadcrumbs were used to smother the haddock in a ceramic dish. The whole lot went in the oven for 15 minutes at 210C... perfect.
