If you're worried about labor, cook using a pressure cooker eg. instant pot. You prepare your ingredients, throw it into a pot, and press a button - coming back to perfectly cooked food with zero monitoring. I work from home and so use mine daily.

Me too. You can even go faster by sealing the food with some insulator (e.g. plastic or tinfoil) to make it retain heat and cook faster in the microwave.

Tinfoil in the microwave? Doesn’t it arc?

That’s what the government wants you to believe.

I don't know the answer to this, but my grandma has an old microwave with a metal grill that your food rests on (like a rack in a conventional oven). I am not sure if it is the type of metal or the shape (it has a squiggly bend on each side, in the middle[0]), but it's definitely possible for metal to go in the microwave without sparking.

I believe that depends whether it's actually tin or instead aluminum.
