“We cooked so much food for Thanksgiving, we’ve been eating leftovers ever since.”
When food is left over from a meal, you can eat it later as “leftovers”. Although most things are better freshly made, there are many foods that are equally delicious when reheated.
「感謝祭にたくさん料理を作り過ぎたから、ずっと残り物を食べ続けてるんだけど。」
食事で残った食べ物は leftovers(残り物)として後で食べます。作りたてのほうが美味しいですが、翌日の方が美味しい場合もあります。
