Prepare the pasta according to package directions. Cook the pasta al dente (not overcooked). Drain and set aside.
While pasta is cooking, melt the butter in a pan. Add the salt, pepper and garlic. Cook for 1 minute. Stir in the white wine and lemon juice. Cook for about 4 minutes or until the mixture is reduced to ¾ cup.
Add the flour and whisk until combined. Saute until a little thicken.
Add in the cooked shrimp and saute until heated through.
To plate: divide the pasta among two plates. Divide and spoon the shrimp scampi on top of the pasta. Garnish with chopped chives or parsley, if desired.
