They seem to be aimed at office workers or campers, or anyone who doesn't have access to facilities to transport and heat milk, or the time to make real porridge.
At £2 a pot they make for quite a pricey breakfast!
Looking at the ingredients they seem simple enough to replicate-Oats, milk powder and sugar.
So to make our vegan version we can just sub the milk powder for soya milk powder, and voila! -instant (vegan) porridge! Just add boiling water!
Much cheaper than the store bought (non-vegan) kind, and easy enough to carry in a little tub, or a zip lock bag. (It can then be mixed with boiling water in a bowl or mug.)
I had a go at making a batch to see how it would turn out...
I ground the oats in a blender first, to make them finer, then added soya milk powder and sugar.
I forget the exact measurements but I think it was something like half a cup of ground oats, one tablespoon of soya milk powder, and one tablespoon of sugar (which in hindsight was probably a bit much!), and then added enough boiling water to make a nice porridgey consistency.
-Obvious additions to the porridge could be: cinnamon, raisins or other dried fruit. I've even seen some shop bought kinds with coconut in!
If I am ever in the unfortunate situation where I can't make a saucepan of porridge with bottled soya milk, this is what I will turn to!
