I rarely eat Wheetabix. My preferred breakfast/supper/general snack is ground or flaked oats in cold water. Pour them in, add cold water from the tap, stir a bit, leave for a minute or so, eat.

It's also very cheap - you can get a big bag of them for buttons and they don't go off for ages. A bugger to clean off stuff if you don't do it soon after eating, but that's true of Wheetabix too.
Or oatcakes. Potteries style oatcakes (which are pancakes), not Scottish style oatcakes (which are biscuits). Although many Potteries people think I'm a bit odd because I enjoy eating oatcakes cold and on their own. It's far more common to eat them hot and wrapped round other stuff that's also hot.
