Cook the pasta according to package directions. Drain and set aside.

Heat the olive oil in a large skillet over medium heat. Saute the chicken breast until cooked through, seasoning with salt and pepper. Remove from heat and set aside in a small bowl.

Return the skillet to the heat, add the garlic and mushrooms. Saute until the mushrooms have cooked through. Use a spoon to remove excess liquid.

Reduce the heat to low and add one jar of marinara sauce, chicken cubes, red pepper flakes and parsley. Let the sauce simmer for about 5 more minutes.

Stir in the fresh mozzarella cubes and let cook for a few more minutes, until the cheese begins to melt.

To serve, place the pasta into four bowls. Top with a sprinkle of shaved parmesan, then ladle on the sauce, and finally add a sprinkle of fresh basil strips.
