Preheat the oven to 350 degrees F (about 180 degrees C).

Prepare the sauce: In a medium stainless steel saucepan, mix together all ingredients until combined and bring to a boil over medium-high heat, stirring occasionally. Pour into a large Pyrex or casserole dish, and set aside.

For the pasta nests: Arrange uncooked pasta nests on top of the hot tomato sauce, keeping each a bit of a distance from the others. Using a spoon, ladle some of the hot tomato sauce over each nest to moisten. In a medium bowl, mix together the cheeses and peas, and set aside.

Pat dry the chicken with paper towels and cut into small pieces. Season chicken pieces with salt and pepper. In a medium non-stick skillet, heat the olive oil over medium-high heat and brown the chicken (about 2-3 minutes). Mix into the cheese-pea mixture. Spoon cheese-chicken mixture into the raw pasta nests. Cover baking dish tightly with aluminum foil (If necessary, grease the interior of the sheet with non-stick cooking spray in order to avoid the cheeses sticking to the foil). Bake for about 40-45 minutes. Remove foil and sprinkle grated Parmesan cheese on top of the pasta nests if desired. Serve chicken casserole nests hot (2 nests per person). A fresh salad or steamed vegetables, if desired, can accompany chicken casserole nests. Enjoy our chicken casserole nests!!!
