Heat a skillet to medium-high. Brown sliced smoked sausage and drain excess grease. Remove sausage to a plate and set aside.
Blend roasted red bell peppers with half and half and garlic powder until smooth. Pour mixture into skillet and bring to a simmer. Once the sauce is warm and bubbly add the pasta, and cooked sausage. Cook for 2 minutes or until everything is warm. Remove from heat and stir in basil. Spoon into serving bowls or plates and use a vegetable peeler to top each serving with parmesan shavings.
