I'm trying to find out the Syn value for Morrisons Eat Smart fat free soy, chilli & ginger dressing. It says it's fat free and SW says fat-free dressings are a free food but do ALL fat-free dressings come under that category? I can't work out the syn calculator as it only gives values for 100ml and when I put it into the syn calculator, it comes out at 2.5 syns - but for what? Confused. I'm new, and really trying. Thanks!
