Hearty biscuits with sausage gravy are definitely a popular item. I didn't care for diner versions even before discovering the dairy allergy. Leftover meat and gravy works well as a home-made way to deal with leftovers, though.

From the ancient family Betty Crocker cookbook:

Add a thick white sauce with lots of browned ground pork sausage mixed in and you'll be close. Caloric overload warning!
