Spicy Cajun Shrimp Spaghetti

Combine 1/2 cup of oil, tomato sauce, 1 1/4 cups of water, fresh basil leaves, a pinch of black pepper, a dash of crushed red pepper flakes, and a sprinkle of salt in a 4- to 6-quart cooking vessel over medium heat. As it begins to simmer, decrease the heat to a lower setting and stir occasionally.

Meanwhile, sprinkle seasoned shrimp with a pinch of salt, a dash of black pepper, and a pinch of crushed red pepper flakes; mix them together thoroughly and set aside for later use.

Warm 2 tablespoons of oil in a medium-sized saucepan over high heat. Add sliced green bell pepper, red bell pepper, onion, and garlic to the pan. Cook and stir until they are slightly softened, taking around 3 to 5 minutes.

Add the vegetables to the tomato sauce and cook over medium heat for a short period of 3 minutes. Lower the heat to low and continue cooking, stirring occasionally, for a total of 20 to 25 minutes.

As the sauce is nearing completion, with around 7 to 10 minutes left until it's finished cooking, add the seasoned shrimp to the sauce; mix them well together. Increase the heat to medium and stir occasionally.

In a small bowl, combine cornstarch and 2 tablespoons of cold water; add the mixture to the sauce when it has around 2 minutes left until completion and mix well together.

Bring a large pot of lightly salted water to a boil. Add pasta to the pot and cook until it reaches the desired level of doneness, taking around 8 to 10 minutes; drain and place it in a serving bowl.

Pour the sauce over the pasta and sprinkle with chopped green onions.
