The first microwave oven that I bought, over 40 years ago, came with a ceramic dish that was "metallised" so that it heated up when being used. It was slightly domed with a deep groove around the edge to collect any grease produced during cooking. A little oil or butter could be used if the item being cooked had no fat of its own, but othe= than that, none was required. I remember really good egg and bacon butties (if you like the egg whites crisp).

It was dropped and shattered into a million pieces. I have never seen one for sale since, but then again, I have never looked for one. I am happy enougb with a frying pan.
