Heat a pot of salted water to boiled, then add the noodles. Cook until almost tender. Drain.
Just before the noodles are done, preheat your oven to 180° C (350° F) and lightly grease a 9x13 baking dish with butter or cooking spray.
While the noodle are cooking, in a large mixing bowl, add the soup, sour cream, and milk, whisk together. (I used creamy chicken mushroom soup, which is an excellent choice.)
Stir in the hot dog slices and peas. (I used mixed vegetables.)
Add the drained noodles to the soup mixture and stir to mix together.
Pour mixture into the prepared baking dish and spread out evenly.
Top with cheese.
Bake for 30 minutes or until the cheese starting to brown. (I baked for 40 minutes, but start checking the cheese browning at 30 minutes.)
Serve and enjoy.
