As either a vegetarian main dish or as a side dish, I like to serve this either way. I just add more mushrooms and asparagus when it is the main dish.
A nice healthy side-dish, which was very tasty with some mashed potatoes! The only modification I made was to use 2 onions instead of an onion and a shallot. We have very uncultured tastes and consider one allium to be as good as another, so I can't say we noticed a difference. I'm sure I will be making this again :-) - 04 Jan 2013
