Boy have things got watered down - from an opinion that we wash and make a berachah on washing every time we pee to not making a berachah when washing even for davening to people not even washing for davening as they would when washing for bread.
Anyway, if someone went to the bathroom in the middle of a meal, it seems to me it wouldn't be wrong to wash with a berachah even if he's not eating more bread since in any event there's an opinion we need to wash with a berachah anyway.
