This was fairly flavorless. It could be doctored up to taste better, but on its own, there's not much to it. We added more lemon juice. If I were to make it again (not likely), I'd probably add some other herbs and spices.
This is a wonderful side dish. I had it with pork chops, carrots and some crusty bread. The bitterness of the lettuce balances very well with the sweetness of the peas. Only change I made, I substituted 1 1/2 tb flat italian parsley for the thyme as I prefer it with peas. Thanks for a nice dish.
