Bake the biscuits according to package or recipe directions until golden brown.
While biscuits are baking, cook the pork sausage in a large, heavy skillet over medium-high heat until completely done and browned.
Remove the cooked sausage with a slotted spoon and set aside, leaving 4-5 tablespoons of fat in the pan.
Add flour to the remaining fat and whisk rapidly to create a roux.
Slowly pour in the milk while whisking continuously to prevent lumps from forming.
Continue whisking until the gravy reaches a thick, creamy consistency.
Taste and season with salt and pepper as needed.
Stir the cooked sausage back into the gravy.
Remove biscuits from oven and split them in half horizontally.
Pour the sausage gravy generously over the split biscuits.
Top with shredded cheese if desired and serve immediately with scrambled eggs.
