Fish en papillote

I like my fish very moist and therefore prefer cooking techniques such as poaching or steaming.  Cooking en papillote is a great method as well.  I like it because it looks and feels fancy, but is extremely easy.  Bonus:  It is a good way to dazzle guests. 

1) Place fish on parchment paper (any kind of fish works well)
2) Thinly slice vegetables such as cherry tomatoes, carrots, green onion, shallots and place on top of fish (although I have seen them placed under the fish, which may actually work better for even cooking of the fish)
4) Dress with herbs and seasoning (e.g., dill, salt, pepper)
5) Add 3 tbsp liquid (e.g., white wine, chicken stock)
6) Bake for about 15 min (until fish is done)
7) Impress guests by opening papillote in front of them and by calling it a papillote
