Cook noodles according to package directions. Meanwhile, sprinkle swordfish with 1/2 teaspoon salt and 1/4 teaspoon pepper. In a large skillet, saute swordfish in oil for 5-6 minutes or until opaque. Using a slotted spoon, transfer to a bowl; keep warm.
In a small bowl, combine flour and cream until smooth; add to the skillet. Stir in the cheeses. Bring to a boil; cook and stir for 2 minutes or until thickened. Stir in the fish, vegetables and remaining salt and pepper. Cook for 5 minutes or until heated through. Drain noodles; top with swordfish mixture.
