- Whisk together the 1/2 cup extra virgin olive oil, 1/3 cup lemon juice and zest, freshly grated cheese, parsley and a dash of salt and pepper. 
- Drain the spaghetti, reserving about 1 cup of pasta water.  
- Return the drained pasta to the pot. 
- Pour the lemon sauce over the drained pasta and toss to combine.  
- Add a little bit of the reserved pasta water if needed. 
- You'll want to add just enough of the reserved pasta water to moisten the spaghetti. 
- Toss well. 
- Transfer the spaghetti onto a serving platter and top with the pan seared shrimp. 
- Sprinkle with a dash of chopped parsley and a drizzle of extra virgin olive oil. 
- You can bring the assembled platter to the table and let everyone help themselves or make individual servings topped with an equal amount of shrimp, a drizzle of extra virgin olive oil and garnished with parsley. 
- And pass the cheese if you wish. I'm all for extra cheese!
