Bring a large pot of salted water to a boil and cook the pasta according to package directions.
While the pasta is cooking, heat the olive oil in a large pan over high heat. Add the shrimp and sprinkle with Italian seasoning, salt and pepper. Cook for 2-4 minutes or until shrimp are just pink and opaque.
Drain the pasta and add it to the pan with the shrimp. Stir in the pesto.
Add the cherry tomatoes and parmagiano-reggiano cheese to the pan. Garnish with chopped parsley if desired.
