What would happen if I were to microwave a non-microwaveable ready meal?Watch
We can't help much if we have no idea what it is...
I'd advise you to cook it for longer at a (somewhat) lower power, so it isn't still cold in the middle. Other than that it should be fine.
If it doesn't work out you know for next time anyway ^^
I think it will be fine, just don't heat it for too long. Might not taste as amazing but will generally be ok
Just don't try and microwave an egg.
Mind you, last time I did it the microwave died and a Scrin raiding party came through a newly formed wormhole in my kitchen.
