A person doesn't often need to enter a code at a microwave if they want to reheat food. They simply program the microwave for how long they want the food to cook after they place the food inside.
yes youcan
Sure you can reheat this food. Make sure the internal temperature comes to 165 degrees. This food can be frozen too.
Yes, they do. Along with many US eateries.
false
Start freezing my own food. Cook ad needed. Rather, reheat the food as needed.
No just to keep it warm until served
because it is already heated so all you have to do is reheat
because its gross to heat it more than once
Yes. Rewarming food only changes its consistency. Eventually it will get tougher and drier.
If food that should have been refrigerated was left out at room temperature overnight, it should be discarded.
If you cook it for long enough, at a hot enough heat, then yes. But you can only "cook" once, then "reheat" once (a reheat is not a full cooking time, just long enough to get it really hot). Do NOT reheat the same meat twice, since it can lead to food poisoning.
