M&S cauliflower mash

[MyCatHatesEverybody]

I saw an advert for M&S cauliflower mash during last week's Britain's Got Talent but can't find anything more about it online. Has anyone tried it or have any nutrition info? I'm wondering if it's low carb or whether they've mixed it with potato like you sometimes see with fresh carrot & swede mash. My nearest M&S is quite a drive away so I don't want to do a special trip if it turns out to be packed with carbs.

I had some a couple of days ago and it a fair bit of sour cream in it.
Can't remember the other ingredients, but it was quite 'tart' almost zingy in flavour.
I was expecting to love it but wasn't sure.

@Weloveoptimus thanks, that's interesting. Was it fairly low carb? I'm thinking I might try it and stir some grated cheese through it to counteract the sharpness.

I hate making home made cauli mash, it takes me an age to get it really smooth despite trying a stick blender, nutri ninja, mini chopper etc.

I've tried it and OMG it is the best thing ever ! Officially now my favourite food. Love it mashed in with some butter and cheddar.
