I would recommend making magic porridge! You get 35g of porridge oats as a HExB, and mix this with a muller light or around 140-150g of free yoghurt and put in the fridge overnight. This makes a lovely creamy thick cold porridge as the oats kind of absorb the yoghurt. If I'm using natural yoghurt instead of a muller I add a tbsp or so of sweetener as well. I then have this with a chopped banana and some defrosted frozen summer berries. I get the berries at asda frozen because they're cheaper and defrost a small handful overnight while the porridge is being magicked. This makes a big, yummy, filling breakfast! My new favourite. And because you're using yoghurt instead if milk it's creamier and you get to save your HExA for cheese / milk later! Alternatively you can make normal porridge with milk as I find this quite filling compared to the cereal allowances x
