It's tricky, isn't it? I try and have chopped fruit with my cereal - bananas, pears, apples all work for me and are reasonably inexpensive. Or I'll follow it up with a couple of satsumas or something.
I don't like fruit mixed in with weetabix either - have to have it before of after eating it. At the moment by breakfast of choice is All Bran, and that works much better for me with fruit mixed in. Either chopped up banana or apple. Delicous and very 'cleansing' lol x
