Really delicious salad dressing found today - Sainsburys Taste the Difference Porcini Mushroom Dressing, bit pricey at 1.99 a bottle, but you dont need much - carbs per 100g - 3.3g - carbs per tablespoonful - 0.5g.

I also love Paul Newman's salad dressings - they are all made with natural ingredients and the profit goes to charity - large Sainsburys stock them.
