Coat your food processor with PAM Canola Oil Cooking Spray. Combine the basil, arugula, parsley, garlic, and pine nuts in a food processor and pulse until coarsely chopped. With the processor running, slowly pour the olive oil into the bowl through the feed tube and process until the pesto is thoroughly combined. Add the Parmesan cheese and pulse again until smooth. Season with salt, taste and adjust any ingredients as necessary. Remove from food processor and set aside.
