For the pasta: Fill large pot halfway with water, add the salt and let the water come to a boil. Add the pasta to boiling water. After 8 to 10 minutes, check for doneness. (Longer boil time will result in softer pasta; shorter boil time will result in more "al dente" pasta.) Remove the pasta from the water and put in serving bowls.
Right before serving, add the sauce to the pasta. Toss until every strand is coated with sauce. Garnish with the sliced vegetables or crushed peanuts. Serve.
