He eats cereal, rain, shine or apocalypse.
LOL, mine too! And he HAS to have yoghurt and juice along with it. Breakfast is his thing.
For the hot breaky though, I'd go with what the other girls have said. Eggs are pretty inexpensive, so maybe he can cook himself some scrambled on toast? And you can buy tins of tomatoes quite cheaply too - a tomato and onion salsa on the side could be a nice treat perhaps...
I love crumpets too, and they seem to be on special at the shops really frequently (cause they only have a couple of days left before they expire). I put them in the freezer and they heat up fine.
