Boil the linguini in a large pot of water according to package directions, then drain the noodles. Mix pesto and broth in a large frying pan, and bring to a low simmer. If using uncooked shrimp, in another frying pan, add 1 tablespoon olive oil over medium heat, add the shrimp, salt and pepper and saute until pink. Add shrimp and noodles to pesto mixture, and mix well to coat. Sprinkle with parmesan and serve.
