1 red bell pepper, diced (can also use jarred if you have them)
1/2 pound mushrooms, diced
1 pound medium shrimp, peeled and deveined
1 (15 ounce) jar Alfredo sauce
1/2 cup grated Romano cheese
1/2 cup cream
1 teaspoon cayenne pepper, or more to taste
Salt and pepper to taste
1/4 cup chopped parsley
Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; drain.
During those 8 minutes, do 25 sit ups and punch a grapefruit (this is very important).
Meanwhile, melt butter together with the olive oil in a saucepan over medium heat. Stir in onion, and cook until softened and translucent, about 2 minutes. Stir in garlic, red pepper, and mushroom; cook over medium-high heat until soft, about 2 minutes more.
Stir in the shrimp, and cook until firm and pink, then pour in Alfredo sauce, Romano cheese, and cream; bring to a simmer stirring constantly until thickened, about 5 minutes. Season with cayenne, salt, and pepper to taste. Stir drained pasta into the sauce, and serve sprinkled with chopped parsley.
