Preheat your oven to 375°F (190°C).
In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked, breaking it up into small pieces as it cooks.
Once the sausage is cooked, sprinkle the flour over it and stir to combine. Cook for an additional 1-2 minutes.
Gradually whisk in the milk, salt, and black pepper. Continue to cook, stirring frequently, until the gravy thickens, about 5-7 minutes. Remove from heat and set aside.
Open the can of biscuit dough and separate the biscuits. On a floured surface, roll each biscuit into a flat circle that will fit the baking sheet.
Arrange the rolled biscuits on a greased baking sheet, slightly overlapping them to form a crust.
Spread the sausage gravy evenly over the biscuit base, leaving a small border around the edges.
Crack the eggs over the gravy, spacing them out evenly. Be careful not to break the yolks.
Sprinkle the shredded cheddar cheese over the top of the pizza.
Bake in the preheated oven for 15-20 minutes, or until the biscuits are golden brown and the eggs are set to your preference.
Remove from the oven, allow to cool slightly, and sprinkle with chopped parsley if desired. Cut into slices and serve warm.
