I combined 2 recipes from a Betty Crocker cookbook. This is my stepsons' favorite dish. I usually keep this for a special occasion such as New Year's Eve or a birthday because it's not light in calories. Everyone who has tried it loves it.
Peel shrimp. Make a shallow cut lengthwise down back of shrimp; wash out vein.
Heat oil in 10 inch skillet over medium heat. Cook shrimp, green onions, basil, parsley, lemon juice, salt and garlic in oil 2 to 3 minutes, stirring frequently, until shrimp are pink and firm; remove from heat.
Heat butter and whipping cream in 2 quart saucepan over low heat, stirring constantly, until butter is melted. Stir in cheese, salt and pepper.
Mix fettuccine, shrimp mixture and alfredo sauce together in large bowl.
