Combine all the ingredients in a bowl (except the sourdough and Philadelphia), adding the vinegar, lemon juice and oil at the end.
Season to taste, it may need a little more salt than you think.
Toast the sourdough and spread thickly with Philadelphia cream cheese. Spoon the green sauce over the top.
Cook's tip: For the herbs, chef Valentine likes parsley, tarragon, basil and mint. You can use Philly Light as a lighter option.
