This is a recipe from America's Test Kitchen: Let's Get Cooking software for the Nintendo DS. A different take on the dressing, fresh parsley imparts an herby flair to the sauce. I think next time I try this, I'll cut up a hard-boiled egg and mix in, as well. Please see the note at the end for more information about the use of sweet pickle in this recipe. I agree with the note on the original recipe - do not use sweet pickle relish instead of regular sweet pickles, the taste would be overwhelming.
