Depending on people-
use 1-2pounds ground breakfast sausage, brown that first.
After that heat on low.
Then you add a cup of milk.
Then add in flour slowly, he puts about a cup full but sometimes doesn’t use it all if it starts to get too thick.
Add salt and pepper to taste, but hold off on the salt until it gets closer to the end. Sometimes the sausage is pretty salty already.
