Meanwhile, for sausage gravy; crumble sausage in large saucepan or skillet, cook over medium heat. Add onion; cook and stir until transparent. Remove sausage to platter reserving drippings.
Stir in flour and cook over medium-low heat till bubbly and golden brown (sometimes I add small amounts of milk so the flour mixture doesn't burn). Stir in milk; add seasonings and continue cooking and stirring until thickened. Serve over sliced biscuits.
