This is like saying that cold beer can be heated? If you want to heat it, why ice it first?

If you change the question to the general ingredients of cold dishes, can you fry them? The answer is yes, such as vermicelli, which is usually cold, but it can be fried to make a thin face.

If your question is whether cold dishes are fried before eating, of course, for example, sweet and sour cabbage, fried first, cold dishes are better than hot dishes. Many cold dishes are overheated first, such as sauce beef, smoked fish and so on.
