OK does anyone have any idea why conventional "breakfast" food seems to so often come with absolutely no vegetables?

Update on this: I feel like this problem has decreased by ~50% since (my memory of) pre-covid, more and more breakfasts have vegetables, especially in East Asia. Still far from ideal though.

Simplez, во время индустриальной революции, ну типа в Англии, выжить было не возможно не поевши утром - работали они физическим трудом по 12-14 часов в день - поэтому bacon, sausage, 2 eggs, 2 half tomatoes fried and baked beans, of course! Комбинация включала овощи)))))
