Probs a bit naughty Stace - check the sugar, carb and fat content of them compared to two Alpen Lights and if it's more or less the same then you should be alright.
That's what I did with the HEb bread rolls - those Hovis ones have 1.5g sat fat compared to the Tesco Healthy Living 57g ones, which are something like 0.2g or 0.4g
Good point Vixxster! Will do. I've only done that once as I've been buying Alpen Lights recently but will deffo compare the two! This week is 100% on plan though and no tweaking!
