square meal

A square meal is a large, healthy meal that makes you feel you have eaten enough.

饱餐;美餐

a square meal 其实和“正方形 square”完全没有关系。在这里，square 我们可以理解为“实在的，真实的”。这个表达的实际含义是“一顿饱饭”，指吃的东西非常丰盛，能够填饱肚子。人们经常会用“three square meals”这个搭配来表示“一天三顿饱饭”。

They haven't had a square meal for four or five days.

他们已经四五天没吃上一顿像样的饭了。

She filled her guests with a square meal.

她以丰盛的一餐来满足她的客人。
