This hearty pasta dish is loaded with pepperoni, mushrooms, and a creamy tomato sauce. To make this dish, you'll need 1 pound of pasta, 1 package of pepperoni, 1 cup of sliced mushrooms, 1 can of diced tomatoes, 1/2 cup of heavy cream, 1/4 cup of grated Parmesan cheese, and 1 tablespoon of olive oil. Cook the pasta according to the package instructions. While the pasta is cooking, heat the olive oil in a large skillet over medium-high heat. Add the pepperoni and mushrooms, and cook for 5-7 minutes, or until the mushrooms are tender. Add the diced tomatoes and heavy cream, and bring to a simmer. Simmer for 5-7 minutes, or until the sauce has thickened slightly. Drain the pasta, and add it to the skillet with the sauce. Toss to coat the pasta with the sauce. Serve hot, topped with grated Parmesan cheese.
