It's not that Asians (specifically for me, HK) don't eat veg, it's that protein is much less favoured as the main ingredient in a dish. This extends practically everywhere, like European countries.
Take for example the prototypical American BBQ: brisket, pulled pork, ribs, and the sides are mac & cheese and cole slaw... Americans don't consider a breakfast proper unless there's bacon or something red meat involved, or I guess if you really have to compromise, eggs.
If there's a breakfast without meat, it's explicitly called a continental breakfast!
