This pesto from chef Sara Foster is used in her Arugula Pesto Snap Beans recipe from "Sara Foster's Southern Kitchen."
Place arugula, cheese, almonds, garlic, salt, and pepper in the jar of a blender or bowl of a food processor and pulse several times to chop. Add lemon juice and pulse until pureed. With the motor running, add olive oil and puree until smooth. Use immediately or store in an airtight container, refrigerated, for up to 1 week.
