Weetabix isn't as healthy as they'd like you to think. 2 Biscuits are 26g carbs and 0.1 g salt before you add in milk (which also has salt naturally).
I find a porridge made with chia seeds, milled flaxseed and oatbran works best for me - with half and half full fat milk and water. I soak the chia seeds and flaxseed in water the night before, stir in the oatbran and milk in the morning and microwave for just over 2 mins (while I am making a drink).
Flavoured with a pinch of salt, vanilla powder.essence and cinnamon.
It can be eaten cold, and it sets fairly firm!
