。
She looked at me.
Literal
She [topic-は] me [object-を] saw.
About as bare-bones as a Japanese sentence gets — topic, object, verb. 見る covers both 'see' and 'look at' depending on context, with the deliberate-action sense ('look at') typical when there's an animate を-marked object as here. The past 見た could be translated as 'saw,' 'looked at,' or 'glanced at' depending on context.
