People actually cook things in microwaves? As in - they go from raw product to a cooked product? I've only ever used and only ever saw microwaves bring used for warming up meals, never for actual cooking.
For some reason the concept doesn't seem popular in many parts of the world, to the point that people don't even realize you could use a microwave to cook things[0]. But it can be, and people do. I even stumbled upon a cookbook once, that was entirely dedicated to cooking in microwave. Very interesting and insightful read. Microwave is a different beast than ovens and stoves, but if you appreciate its nature, it turns out you can do quite a lot of cooking with it.

[0] - This is a funny thought pattern failure that's common for people, and I don't know the better name than "acute lack of problem-solving abilities" for it. I mean, people should realize that cooking happens through heat, and microwave adds heat into a product, hence it can technically be used to cook...
Well, it's certainly doable. Though for meat in particular, people prefer to use stoves, grills, and ovens, because while a microwave can heat up meat to the point where it cooks, you really need a grill or a hot pan, for example, to induce the Maillard reaction on the surface of a steak (give it a good sear), while leaving the inside medium-rare. Try doing that in the microwave...
What buttons? Pretty much every microwave I've ever seen looks like this[0] - timer + power setting. Even our kitchen at work which has some really fancy microwaves only offers time + power, nothing else. The ones full of buttons on the front are from like....American movies, not something I ever see in real life :P
