-You can substitute whole wheat pastry flour for an extra hearty, more chewy gnocchi.
-For the Olive Oil Sauce, you can use any fresh herbs you have on hand. Instead of or in addition to the ones in the recipe above, you can use parsley, basil, sage, or bay leaf. As long as you use around 3 different ones, it'll be great--whatever the combination.
-Make sure to toast your walnuts! They add a rich complexity that really does complete the dish.
