1-1/2 cups uncooked penne pasta
1 tablespoon canola oil
1 pound boneless skinless chicken thighs, cut into 1-inch pieces
1/2 cup chopped onion
1/2 cup chopped green pepper
1/2 cup chopped sweet red pepper
1 teaspoon dried basil
1 teaspoon dried oregano
1 teaspoon dried parsley flakes
1/2 teaspoon salt
1/2 teaspoon crushed red pepper flakes
3 garlic cloves, minced
1 can (14-1/2 ounces) diced tomatoes, undrained
3 tablespoons tomato paste
3/4 cup chicken broth
2 cups shredded part-skim mozzarella cheese
1/2 cup grated Romano cheese
Minced fresh parsley, optional
Preheat oven to 350°. Cook the pasta according to package directions. Meanwhile, in a large saucepan, heat oil over medium heat. Add the chicken, onion, peppers and seasonings; saute until chicken is no longer pink. Add garlic; cook 1 minute longer.
In a blender, pulse the diced tomatoes and tomato paste, covered, until blended. Add to chicken mixture. Stir in broth; bring to a boil over medium-high heat. Reduce the heat; cover and simmer until slightly thickened, 10-15 minutes.
Drain pasta; toss with chicken mixture. Spoon half of the mixture into a greased 2-qt. baking dish. Sprinkle with half of the cheeses. Repeat layers.
Cover and bake 30 minutes. Uncover; bake until heated through, 15-20 minutes longer. If desired, garnish with parsley.
