1/4 teaspoon kosher salt, plus more for cooking the pasta
1 1/2 cups skim milk
Heat the oven to 350°F and arrange a rack in the middle.
Bring a large pot of heavily salted water to a boil over high heat. Add the noodles, stir, and cook until al dente or according to the package directions. Drain and set aside.
Place the cottage cheese, sour cream, margarine, eggs, sugar, vanilla, and measured salt in a large bowl and whisk until evenly combined. Add the noodles and stir until incorporated. Pour the mixture into a 13-by-9-inch baking dish and spread into an even layer. Pour the milk all over the top of the noodle mixture.
