This reminds me of Nigella Lawson's Hangover Eggs, which is a big favourite in this house and I've spoken about on here before. The ingredients are different, but the method is v similar. Like you say above, not having to do a lot of chopping and things is great in a lot of situations (including being hung over).

My favourite instruction in this is "Stir around until reduced enough that the spinach no longer comes over the top of the pan.".
