Boil water in large pot for noodles. When the water is in a rolling boil add the noodles. I like to add a pinch of salt so that the noodles won't stick together.
In a second smaller pot, add cream of chicken soup. Then add peas. With the can from the peas fill it with milk only once, add that. Then add the stick of butter. Let it simmer over low heat until nice and creamy. Then add salt and pepper, garlic powder, minced onions, and the other seasonings you like.
When the noodles are done, add what's in the smaller pot, and mix together.
