02 - Combine arugula, pine nuts, garlic, olive oil, and Parmesan cheese in a blender or food processor. Blend until smooth and season to taste.
03 - Heat a large skillet over medium-high heat. Add the shrimp and sauté for 2 to 3 minutes per side, or until pink and opaque. Remove from heat.
04 - Toss the drained pasta with the shrimp and arugula pesto, stirring gently to combine. Serve immediately.
