。
My mother tells me to eat more vegetables.
Literal
Mother [topic-は] me [to-に] more vegetables [object-を] eat-[imperative-ろ] [quotative-と] says
食べろ is the plain imperative of 食べる — direct and commanding. と言う in the present tense reads as a habitual 'says,' framing the mother's dietary instruction as something she repeats often rather than a one-off remark.
