Bake or reheat biscuits according to package instructions.
Heat a large pan over medium heat. Remove breakfast sausage from its wrapping, and sauté until crumbles are cooked through.
Add in flour and stir to coat. It should absorb some of the oil and stick to the sausage.
Add in the milk by half cups, stirring and allowing to thicken.
Reduce heat and simmer 1-2 minutes, stirring constantly.
Season with salt, pepper, and hot sauce as desired.
Split biscuits in half, and top with gravy. Serve hot with other breakfast foods
