Dover sole

[TomK]

Thanks for the replies. I agree with Kalianna that halibut is a bit too meaty and think the biggest problem is that the fillets are thick which makes stuffing difficult, but it's a very nice tasting fish. As for tilapia, it looks similar to sole but I find it quite tasteless, but might try it as a practice run and you never know, it might work.

Turbot is the ideal substitute, but like Dover sole, it's a northern Atlantic fish and I've never seen it for sale here.
