I have an original porridge and a chocolate together...and make it REALLY thick, so it kinda ends up like a strange flapjack style thingy. Its yummy or maybe im just strange hehe
I chuck it in a bowl, boil the kettle, add water (I have no idea how much, I never measure it), then mix with a spoon and microwave it. I think I probably add more water than it says on the packet as mine is quite runny - with lumpy bits - but I like it like that!
