Or otherwise known as bircher muesli. My very first attempt at this no-cooking-or-heating required and it was a success!
1/3 cup of quick cooking oats (you can use rolled oats)
1 cup of soy milk (I used 1 cup because I didn't have yogurt; else it should be 1/2 cup of each)
Handful of raisins
1 tsp of chia seeds
Granola for topping and crunch
Everything (except the granola) goes into the bowl, cover with cling film and refridgerate it overnight (or at least 2 hours).
