Recipe Instructions

Step 1

Fill a large pot with lightly salted water and bring to a rapid boil. Cook egg noodles at a boil until tender yet firm to the bite, 7 to 9 minutes. Drain.

Step 4

Spread the tuna-noodle mixture in a single layer over the crushed chips. Layer with 1/2 of the mozzarella, 2/3 of the remaining chips, followed by the remaining butter, chips, milk, and mozzarella.
