Bring a large pot of lightly salted water to a boil. Cook egg noodles in the boiling water, stirring occasionally until cooked through but firm to the bite, about 5 minutes. Drain noodles and return to the pot. Pour olive oil and salt over the drained noodles; stir.

Preheat oven to 350 degrees F (175 degrees C).

Put processed cheese food cubes into a large, microwave-safe bowl. Heat in microwave, stirring every 30 seconds, until melted and smooth, 3 to 5 minutes; pour over noodles and add tuna, peas, celery soup, mushroom soup, and black pepper. Stir to coat noodles completely; pour into a large casserole dish. Sprinkle Parmesan cheese over the top of the noodle mixture to cover completely.

Bake in preheated oven until Parmesan cheese just begins to brown, 20 to 30 minutes.
