Can anyone help me work out the syns in M&S king prawns with a basil pesto dressing? I think they are new. Per 100g: Cals 141 Fat 8.1g Of which saturates 1.2g Carbs 0.5g Of which sugars 0.3g Fibre <0.5g Protein 16.4g The pack contained 140g and I ate the lot. Prawns were 78% of the pack. I’m hoping they are no more than 4 syns but am panicking now. Thanks you in advance.
