Boil egg noodles in the water until tender. Drain and place in 13x9x2 baking dish.
Mix in soup, milk, tuna or chicken with the egg noodles. Mix well. Top with cheese and then potatoes chips.
Place in oven at 350 until warmed through.
I add less milk to make it thicker, more cheese then 8oz (cause really, who doesn't love cheese) and only about half the bag of chips. I have evan added a couple of cans of mixed veggies to make it into a complete meal.
