Balsamic Chicken Pasta

12 oz. whole wheat penne pasta (or pasta of your choice)
1/2 cup olive oil
1/2 cup balsamic vinegar
1 1/2 cups tomatoes, diced (if no fresh are available, you can use canned)
1 cup yellow bell pepper, diced
1/2 cup scallions, minced
3 cups chicken meat, cooked and cubed (can also use canned chicken)
1/4 cup fresh basil, chopped (I usually use a tablespoon or so of dried)
4 oz. feta cheese, crumbled
1/4 c. parmesan cheese, grated
salt and pepper to taste

Cook pasta.  Drain and place hot pasta in a large bowl.  Pour olive oil and balsamic vinegar over pasta.  Add remaining ingredients and toss well.  This dish can be served either chilled or hot.  If serving it hot, I usually sauté the bell pepper until it is tender, then throw everything into a large sauté pan to heat it all up.  This is a delicious, healthy, Mediterranean-style dish.
