Three Cheese Chicken Penne Florentine

This is one of my favorites.  It might seem a little complicated, but if you do some prep work ahead of time, it's not bad.  I usually just buy a rotisserie chicken instead of cooking my own.  I also usually add extra spinach, and sometimes I skip the red bell pepper.  You can assemble it and freeze it too.

Three Cheese Chicken Penne Florentine (from Cooking Light magazine)

• 1  teaspoon  olive oil
• Cooking spray
• 3  cups  thinly sliced mushrooms
• 1  cup  chopped onion
• 1  cup  chopped red bell pepper
• 3  cups  chopped fresh spinach
• 1  tablespoon  chopped fresh oregano
• 1/4  teaspoon  freshly ground black pepper
• 1  (16-ounce) carton 2% low-fat cottage cheese
• 4  cups  hot cooked penne (about 8 ounces uncooked tube-shaped pasta)
• 2  cups  shredded roasted skinless, boneless chicken breast
• 1  cup  (4 ounces) shredded reduced-fat sharp cheddar cheese, divided
• 1/2  cup  (2 ounces) grated fresh Parmesan cheese, divided
• 1/2  cup  2% reduced-fat milk
• 1  (10 3/4-ounce) can condensed reduced-fat, reduced-sodium cream of chicken soup, undiluted

Preheat oven to 425°.

Heat olive oil in a large nonstick skillet coated with cooking spray over medium-high heat. Add mushrooms, onion, and bell pepper; sauté 4 minutes or until tender. Add spinach, oregano, and black pepper; sauté 3 minutes or just until spinach wilts.

Place cottage cheese in a food processor; process until very smooth. Combine spinach mixture, cottage cheese, pasta, chicken, 3/4 cup cheddar cheese, 1/4 cup Parmesan cheese, milk, and soup in a large bowl. Spoon mixture into a 2-quart baking dish coated with cooking spray. Sprinkle with remaining 1/4 cup cheddar cheese and remaining 1/4 cup Parmesan cheese. Bake at 425° for 25 minutes or until lightly browned and bubbly.
