Prawn and Fish Couscous

This is ok, but ...

• Serves 4? Don't think so. I made more or less a whole recipe. The two of us ate it all; it might stretch to 3 with a salad or some kind of side dish.
• The shrimp never get cooked per the instructions. I had frozen, cooked ones. Just put them on the sheet with the cod as it baked.
• Had some lovely, fresh green beans, so I cut them in short bits, more or less pea-sized, boiled them for a bit and used those instead of peas.
• My chicken stock was unsalted and I forgot to compensate. Thus contributing to a lack of flavor. Interesting idea, but needs some flavor oomph.
