1/3c. of pine nuts (if you don't like nuts you can omit them, but they give the pesto a more complex flavor...once I was out of pine nuts and used some roasted almonds I had on hand, it was delicious!) and 4 cloves of garlic....take them for a whirl..
Add 2 c. of the green stuff
1/2c. pecorino romano cheese and 3/4c. of parmesan, salt/pepper to taste
Add olive oil while the food processor is running (I eyeball it till I like the consistency but approx. 1/4c.) In the meanwhile cook up your favorite pasta (I use spaghetti) al dente.
Toss and serve from cute bowl that my Momma painted for me! :)
