How do you make microwave oatmeal?

I always cook my oatmeal in the microwave because it only takes 90 seconds! All you do is mix together quick cooking oats and milk (plus ground flaxseeds and cinnamon if you want extra fibre and flavour), cover with a microwave cover, and microwave for 90 seconds. Then mix in more milk until you reach a consistency you like, and top with whatever toppings you like.

Overnight version (for busy mornings):

If you want to make this recipe even quicker to make in the morning, simply mix together the oat/milk/flaxseed/cinnamon in a small serving bowl, cover, and place in the fridge the night before. Then all you have to do in the morning is microwave it for 90 seconds and add in extra milk and toppings!
