How to Make It
Cook pasta according to package directions, omitting salt and fat. Drain. Place pasta in a large bowl; keep warm.
Melt butter in a large skillet over medium-high heat. Add onion; sauté 3 minutes, stirring occasionally. Add garlic and tomatoes; sauté 2 minutes, stirring constantly. Sprinkle shrimp with Cajun seasoning, red pepper, and salt. Add shrimp mixture to pan; sauté 3 minutes or until shrimp are almost done; remove from heat. Stir in half-and-half. Pour shrimp mixture over pasta; toss. Sprinkle with parsley.
Wine note: Linguine with Spicy Shrimp combines peppery heat with a creamy sauce, making a fuller-bodied white a good partner. Little Penguin Chardonnay 2008 ($6), from Australia, has tropical and pear fruit, with just a bit of sweetness and refreshing acidity. --Jeffery Lindenmuth
