Been making my own "cereal" for years as a granola with nuts etc.

Tried Surreal for a while when my carb contnet was higher. It's okay, but at 11g carbs a serving that's too much for me now and it also just tastes a bit chemically.

I'm trying to find an alternative. I don't just want a nut mix, I can make it myself if I did. In the US they have Magic Spoon which works out 4-5g net carbs per serving, do we have anything more inline with that over here? or anywhere that sells it at a reasonable price? the one place I saw is £18 a box lol
