Seems right to me. There are a bunch of ways to make it. I think Matt is against using potatoes (the original recipe was just fish) but both the recipes I usually make involve a pound of fish and a pound of potato.
Is the parsley just for garnish? Might want to throw a bay leaf in when you're cooking the potatoes.
edit: I haz good memory; potatoes
