I have developed an unhealthy obsession with the M&S granola and yoghurt pots and at £1.30 a pop it is not doing my bank balance any good.
So I've made Nigella's and it is yummy, recipe here. I am going to eat it with yoghurt tonight. Helpfully Julian Graves near me has an everything half price sale on so I got a few of the ingredients there. By the way the raisins are supposed to go in after you've toasted the granola. Don't forget or you will spend 15 minutes picking them out of a honey, syrupy, oat mixture!
