there is a prize for anyone who can predict what i want to reply to this! 
What with us actually being closer to France?
I can't imagine...

Let me have a go.

Sorry WVgirl REAL French dressing is nothing close to what's sold in the USA...though I am sure you meant that you miss the American Kraft Food French dressing...or the Catalina style which actually is quite easy to make!
It's a basic vinaigrette with ketchup base...you will have to play with it to get the flavor you want. That or just stock up when you go home as even the US brands here sell a more herby and Tarragon based dressing (probably a bit more French to be honest than Kraft!)
I hope one of these helps you get your fix!
