Just intrigued to why the question is addressed just to " Americans and maybe Germans"
Fried egg, bacon, & sausage 'Banjo'* with ketchup (more often just called 'tomato sauce' here) from a roadside trailer is a staple in the UK. Though Real Men eschew ketchup and slaver the wad with brown sauce.
*So named because as the runny contents inevitably squirt onto the eater's front, they will brush at the besmirchment with one hand whilst holding the offending sandwich at arm's length therefore adopting the stance of a banjo player. The term originally coined by Squaddies.
