Agree... beans are so cheap and easy to prepare I'm surprised. And poached eggs v fried eggs.. again, I would have thought the later would be easier to prepare (happy to accept I know nothing about food prep on a train - I can barely do it in the comfort of our own kitchen).
Worth noting, the picture in the publicity shots shows a boiled egg.. I would have shown a poached egg, cut in half with a delicious yolk oozing out.
Worth noting, the vegan option does have beans, albeit, not Heinz !!!
