A blueberry is also not a meal. And can be served cold if refrigerated. Nothing implies the food can’t be warmed or cooled so that question isn’t great to begin with.

If you just asked, “is it a meal” it would have said no, and implied as much when it said “___” is not a meal.

If you asked “is it a fruit” it says yes.

You asked the wrong questions and got upset when it gave the right answer.
