Cook the pasta according to package directions, omitting salt and fat.
While pasta cooks, heat 1 tablespoon oil in a large skillet over medium-high heat. Sprinkle 1/2 teaspoon of salt and 1/8 teaspoon of black pepper evenly over shrimp. Add shrimp to pan; cook 1 1/2 minutes on each side or until done. Remove from pan.
Add remaining 1 tablespoon olive oil to pan. Add onion, garlic, and red pepper; cook 2 minutes, stirring frequently. Add tomatoes, and cook 3 minutes or until tomatoes begin to soften, stirring occasionally. Stir in pasta and shrimp; cook 1 minute or until thoroughly heated. Remove from heat, and stir in 1/4 teaspoon salt, 1/8 teaspoon black pepper, cheese, and basil.
