In Germany heavy dark bread, cheese and cold meats are often considered standard stuff to start the day with, while in Scandinavia cod roe paste may be spread on toast rather than jam or chocolate spread.
So this is what the English and Spanish breakfast have in common… nothing to do with calories or healthy eating!
In French breakfast is a "small lunch", and Italian and Portuguese words have similar meanings.
In German it is an "early piece".
In Norwegian and Swedish it is literally an "early meal", while in Danish it is "morning food".
But both in English and Spanish the meal breaks a fast… and now you know.
