How about something we have done a few times:
Buy Salmon steaks, make a parcel out of foil (fold a sheet of foil in half and fold firmly along the side edges a few times - this makes an envelope), slide in the Salmon, add some crushed garlic, some white wine and lemon juice, season to taste, then seal the open end by folding firmly a few times. Stcik it on the BBQ and it puffs up as the Salmon is poached in the wine and odds n sods. After about 10 mins, carefully open one end, pour out some if the juices into a pan (reseal the package) and add cream to the pan, simmer it up and reduce to a nice sauce (maybe add some dill?). Serve and watch the poor sods camped near by drool...
Is easier to do than to describe.
Trying to slice an onion one year with a knife on a bottle opener was a laugh. Ended up with a good 'au poivre' sauce to go with the steaks that night tho'. I had the 'Port and Roquefort' sauce instead

Couldnt be arsed to cook properly this year tho
