Prepare the noodles according to the package instructions, cool, and set aside in a bowl.
Toss the shrimp in a bowl with the salt and red pepper flakes. Heat the oil in a heavy pan over medium-high heat. Add the shrimp and saute for 1-2 mintues until the shrimp turn pink. Set them aside.
Add the onion to the skillet and cook until translucent, about 5 minutes. Add the tomatoes with their juices, along with the garlic and oregano. Saute 1-2 minutes more.
Return the shrimp and their juices back to the pan, and toss to coat. Cook for about a minute, then stir in the parsley and basil.
Season with more salt if needed, and serve over the noodles.
