I've seen this around a lot on twitter, people rave over them, so I thought I'd give them a go as other than alpen light bars I struggle with my B option some days and usually only have a muller light and a banana for my breakfast.
So it's just, your 35g of porridge oats - B option
fruit - I used blueberries.
layer them in a jar, pot, bowl...
let them stand overnight.
Will let you know how they are in the morning :)
