For what it's worth, i was at a small conference hotel outside Kansas City this Tuesday. The breakfast bar had a sad pastry basket and a bowl of plain Greek yogurt cups. I grabbed two, stirred in a packet of peanut butter I keep in my laptop bag, and ate it while answering emails.
Usually I skip breakfast and then raid the snack table at 10:30, but that yogurt plus coffee got me to lunch without the vending machine detour. The texture was not fancy, kind of thick and tangy, but it did the job. I tried the flavored one another morning and it tasted like melted candy.
Plain with peanut butter is now my road default. Anyone else have a weirdly reliable breakfast that only works while traveling?
