Same, never eat before the commute (apart from the occasional pick when making the sandwiches). Sometimes knock back a Berocca in the morning, but this isn't anything to do with the cycling.
My favourite 'everyday' breakfast is a hybrid of (No added sugar) Alpen mixed with Scott's Porage Oats, boiling water poured in the bowl, and as it begins to thicken a little honey mixed in.
Alas I'm not in a nice contract where I can cycle in currently, haven't been on the road bike for around three weeks. Seriously dying to get back on. Maybe a nice ride this weekend...
