The instant-meal #food brand Leguerme (seemingly from #turkey) is now available in some Norwegian towns. They have two types of bags, one for Borlotti beans, and one for pasta. They look the same at first glance.
The pasta bag is supposed to be heated in the microwave, and succeeds at it.
The Borlotti bag claims it can be consumed "heated or not". If heated in the #microwave, it will CATCH FIRE after 20sec.
I was lucky to still have a functional microwave after spotting it quickly enough.
