Step 1

Fill a large pot with lightly salted water and bring to a rolling boil over high heat. Once the water is boiling, stir in the egg noodles, and return to a boil. Cook the pasta uncovered, stirring occasionally, until the noodles have cooked through, but are still firm to the bite, about 5 minutes. Drain well in a colander set in the sink.

Step 2

Preheat an oven to 350 degrees F (175 degrees C). Spray a 9x13-inch baking pan with cooking spray.

Step 3

Melt the butter in a skillet over medium heat. Stir in the onion, celery, carrots, and red bell pepper; cook and stir until the onion has softened and turned translucent, about 5 minutes. Stir in the noodles, cream of chicken soup, sour cream, Cheddar cheese, corn, and cooked pork, then season with salt and black pepper. Transfer mixture into the prepared baking dish. Sprinkle bread crumbs on top.

Step 4

Bake in the preheated oven until bubbly, 30 to 35 minutes.
