This is from Nigella Bites - Nigella's rendition of Elvis Presley's renowned Fried Peanut Butter and Banana Sandwich. I had it with my favourite comfort drink, Ovaltine, but I felt like I really should be washing it down with vodka and valium.
It's just a grilled cheese sandwich, except instead of the cheese you put in peanut butter and a mashed up banana. And if you are a whole wheat girl regularly, you have to use white for this. Don't fight it - don't fight the white.
