Prepare the biscuits according to package directions.
Heat the oil in a large nonstick skillet over medium high heat. Add the sausage; cook 3 minutes or until browned, stirring to crumble.
Remove from heat, cool slightly. Crumble the sausage into 1/2" pieces, and return to the skillet.
Lightly spoon flour into a dry measuring cup, level with a knife. Mix the flour and milk, stirring with a whisk until smooth. Add the milk mixture, salt and black pepper to pan; bring to a boil over medium high heat.
Cover, reduce heat and simmer for 3 minutes or until thick.
Split biscuits in half. Place 2 biscuit halves on each of 8 plates, top each serving with about 1/3 cup gravy.
