Bring a large pot of water to a boil, salt it, add the noodles and cook until al dente. Drain, reserving 1 cup of the pasta cooking water.
In a large skillet, heat the EVOO, 4 turns of the pan, over medium-high heat until rippling. Add the bell pepper and cook, stirring occasionally, for 3 minutes. Add the scallions and garlic and cook for 2 minutes. Add the shrimp and cook until pink, about 2 minutes.
Add the noodles to the shrimp mixture; toss to coat. Add the parsley, sherry, soy sauce and a little hot sauce. Stir in the reserved pasta cooking water. Top with the nuts.
