Get your pasta water going. Start the scampi sauce when you drop your pasta into boiling water to cook.
Heat a large skillet over medium high heat. Add extra-virgin olive oil and melt the butter into it. Add shallots and cook a minute or 2, stirring constantly. Add lemon zest and shrimp and heat shrimp through, another minute or two. Add vermouth or wine and tomatoes. Toss another minute to heat the tomatoes through. Add cooked pasta to the pan and toss to coat evenly in sauce and to distribute the shrimp. Season liberally with salt and pepper and serve with chives to garnish.
