Thanks, everybody, for the great suggestions.
Our guest is from Beijing. I asked her on her arrival what she likes to eat for breakfast. She replied, noodles, and tomatoes and potatoes. I have served noodles a couple of times and they seem to go down well. Tomatoes are not in season here at the moment (New Zealand) and 'potatoes' is a possibility I guess: I've just stumbled across a breakfast recipe where one pan fries leftover mashed potato like a big pancake.
So far to our guest I've served a variety of other breakfasts. I figure I would like to showcase some Western food. Our own family eats separate light breakfasts - cold cereal, quick oats, and toast, which are not substantial enough
I've actually really enjoyed the discipline of preparing hot breakfasts, and eating some of these myself! What I have served so far is: spiced oats porridge, lots of egg dishes (omelette, French toast, scrambled eggs), a great deep fried eggs dish I know:

I had found congee as a suggested breakfast for Chinese guests online. It looked all very mustachian (cheap, filling) but then I saw the cooking time was an hour and a half! (I don't have a slow cooker, nor a rice cooker.) So that deterred me, but surely there's a shortcut recipe somewhere ...
I like the idea of omelette with flour and greens too.
