Salad dressing help, please?

I'm at work and I need to get some salad dressing at lunchtime (from a small Co-op), but my book is at home ...... somewhere

I will turn the house upside down and inside out tomorrow, but for now can anyone tell me of a tasty but not overpowering free (if possible) one.

Am I right in thinking one of the Kraft ones is free?

I like the Asda Good for You Italian style dressing which is free. Kraft do a French and an Italian fat free dressing which are both free. Sorry this is way later than lunchtime!
