This was great Heather! The perfect start to our Sunday lunch. It was easy to put together and the dressing was tasty, with a hint of mustard and the onions standing out. I didn't use nearly as many mushrooms as your version calls for though -- I found half that amount was just right.
Very nice salad, couldn't find any arugala or watercress, but I did find some lovely fresh mesculin (baby greens) and actually cut the first chives from the herb garden, barely up 4 inches, all very good! Cut the recipe in half , just two of us, didn't seem to make any difference, the taste was sutle, mustard, onion ,egg and chives, didn't overwhelm the mushrooms. We will do this one again, thanks for sharing.
