3 tablespoons olive oil
2 bay leaves
1 1/2 tablespoons Italian seasoning
1 teaspoon chopped garlic
salt and pepper to taste
4 skinless, boneless chicken breast halves 
1 green bell pepper, chopped
1/2 onion, chopped
1 head broccoli, cut into florets
1 cup finely chopped carrots
1 pound uncooked Penne pasta
5 ounces shredded Colby-Monterey Jack cheese
1 (16 ounce) jar spaghetti sauce

1. In shallow non-aluminum dish or resealable plastic bag, combine olive oil, bay leaves, Italian seasoning, garlic, salt, and pepper. Poke holes in chicken breasts and add to olive oil mixture. Marinate in refrigerator for 1 to 2 hours.
2. Preheat oven to 375 degrees F (190 degrees C). Remove chicken from refrigerator and cut into half-inch pieces. Cook in large skillet, with marinade, until chicken is light brown and sauce is bubbly. Remove bay leaves. Stir pepper, onion, broccoli, and mushrooms into skillet and allow to simmer until tender, about 5 minutes.
3. While vegetables are cooking, 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. Return pasta to pot and add chicken mixture and spaghetti sauce. Stir. Pour mixture into 9×13 inch pan. Top with shredded cheese.
4. Bake in preheated oven for 20 minutes, or until cheese is melted. Serve.
