Food that is packaged so you need a tool kit to open it. I bought a microwavable breakfast wrap the other day.
1. The package it comes in is not microwavable. It could have been, but it isn't. So you have to transfer it to a plate first
2. The film that covers it cannot be peeled back. It's "designed" that way. So I'm standing in the kitchen at work, have to go back to my office. Grab my car keys, walk back to the kitchen and puncture the film to pull it off. So I can put it on a plate.
Very tasty but won't buy again.
