I guess I am from the lazy group of cooks. If I am making a large amount I buy the Morrison's gravy mix--3 bags to a box-recipe on each bag from Sam's you just add water. I cook my Owen's regular sausage- my preference make my gravy then add my sausage, and lazy me I use canned biscuits- I put my gravy and sausage in my large crock pot and take it to Church for our fellowship after church along with my biscuits- everyone loves it.
This is not sausage biscuits and gravy- but here is my chili queso recipe - large box of velvetta cheese, 1 lb of Owens hot sausage, can o golden mushroom soup, 1 can of Rotel original. Melt cheese in a large crock pot, add cooked sausage, Rotel and soup. My family loves it.
