While the pasta cooks, mix the olive oil, lemon juice, dijon mustard, garlic, salt and pepper in a large bowl.
Once the pasta is done cooking, allow it to cool before adding it to the large bowl with dressing. Add the arugula, parmesan cheese and pine nuts. Enjoy!
Notes
For additional protein, you could add chicken or salmon. If you want to keep the recipe vegetarian, tofu is a great option!
You can absolutely enjoy it a few days post-prep; however, the oils will solidify in the fridge. If you plan to serve leftovers to guests, highly recommend taking the salad out of the fridge an hour or so before serving to allow the oils to become liquid again.
