Preheat the oven to 350 F
Cook the noodles in a large pot of salted boiling water according to package instructions. Drain and set aside. Do not overcook them.
While the noodles are cooking, combine cream of chicken soup, cream of mushroom soup, sour cream, paprika, dry minced onion, parsley, oregano, salt, and pepper in a large bowl until smooth.
Mix in the diced chicken, cooked noodles, and frozen peas.
Place the mixture into a 9x13-inch baking dish.
Sprinkle the shredded cheddar evenly over the chicken/noodle mixture, cover with foil, and bake for 30 minutes or until the filling is hot and bubbly and the cheese is melted.
