I make this all the time. Have subs[filtered]uted almost all the ingredients orange juice for lemon...any kind of bread for pita...almonds or pistachios for walnuts...each time is delicious as the first. Very versatile and delicious. Always gets rave reviews. Use leftover sauce on penne pasta the next day with a grating of Parmesan and you're golden.
I love this dip! Highly recommend it. It's beautiful and delicious. I used whatever nuts I had, which I've learned with pesto works well. Great to make a day ahead or morning of so the flavors mingle.
This recipe is simply wonderful and easy to make. Also, I have tried it on sandwiches for a little kick.
