First, cook the pasta according to the package directions until the pasta is tender. Drain the pasta in a colander and then set it aside for just a couple of minutes while you prepare the rest of the dish.

Heat the olive oil in a large non stick skillet over medium high heat. Add the garlic and cook 2 minutes. Add the tomatoes and yellow pepper to the pan and cook an additional 6-7 minutes or until the peppers are tender.

In a large bowl, toss together the pasta, tomato mixture, basil, pepper, salt, and cooked chicken if using that. Lightly mix the ingredients using a large spoon. Then, gently stir in the mozzarella cheese until the cheese begins to melt and becomes very flavorful. Serve with a green salad.
