Step 1

Preheat oven to 450°F. Cook egg noodles according to package directions. Reserve 1/2 cup cooking water, drain and return to the pot. Stir in soup and up to 1/2 cup reserved cooking water, 1 tablespoon at a time, until desired consistency is reached.

Step 2

Meanwhile, heat oil in a small pan over medium heat. Add onion and celery. Season with salt and pepper. Cook, stirring occasionally, until vegetables are soft, 5 to 7 minutes. Add vegetables, cheese, tuna and peas to pot with noodles and stir to combine. Transfer to a 9-by-13-inch baking pan and topped with potato chips.
