This was from the Time Life Scandinavian cookbook, and was one of my healthy vegetable based dishes for Eurovision. Healthy, plus cream. Of course.
I’ve just noticed the bit about the lettuce. I completely missed that part and was very confused about why I had a whole lettuce left over the next day. This was quite nice dish, though I feel the name should reflect that the mushrooms are cooked and that’s it feel more like a solid side dish than a salad, but it was ok.
