"This is a Sara Moulton recipe. She was introduced to the dish in the mid-seventies when she was dating her now-husband who is Jewish. She thought it was a wonderful "breakfast" dish -she started playing around with Boursin cheese - she likes putting the onions on top but we like our onions in and out - so that was a slight tweak! Foodnetwork.com/eda/recipe. I think that next time I'll try it with mushrooms! :)..."
