Make the pesto. Place all of the ingredients, expect for the olive oil, into a food processor. Pulse a few times, then while the food processor is running continuously add in the olive oil in a slow and steady stream until it is emulsified and you have the consistency you like. I find it is usually perfect at around 1/2 cup. Taste and adjust any seasoning accordingly.
Place your pesto into a small bowl (or an airtight container) and place in the fridge until you're ready to dress the pasta.
Cook the pasta according to the package, but be sure to add several tablespoons of salt to the water to season the pasta, and also drain the pasta 1-2 minutes prior to the time recommended on the package to ensure you achieve a more al dente texture.
Place the cooked pasta into a large serving bowl and toss with the pesto. Add the peas, fresh arugula, and parmesan on top and serve.
