Yep, I eat a lot of porridge and this concoction blasts me through the morning until evening.
And remember, these weights below are just a guide, it's porridge, your brekkie, you do not really have to weight it out just guess :-)
Soak the oats over night in 200 ml of the milk of choice along with 20g of grated chocolate. (Optional, you can just go ahead and do this first thing in the morning)
Tip: Soaking the oats over night makes it quicker in the morning. Also add any fruit you like, extra berries, fried bananas etc. For that extra goodness add some protein powder as I do.
