According to a French cookbook I found years after first making this, this simple recipe is fairly common in France. But who cares - it tastes great... It's fast and easy - just remember NOT to defrost the peas.
Mom gave me 3 things to take to college: an iron, a clothes drying rack ("Don't waste your quarters in the dryer"), and a Reader's Digest cookbook that contained this recipe. My first reaction was "This is strange - boiled peas and lettuce?" Kurt had the same reaction - before he ate ALL the leftovers.
