1. Preheat oven to 425°F. Warm a skillet over medium heat. Add sausage; cook, breaking it into small pieces and stirring until no longer pink, 6 to 8 minutes. Drain on paper towels.
2. Combine flour, baking powder and salt. Use a pastry cutter to cut in butter until mixture resembles coarse sand. Gently stir in sausage, milk and herbs.
3. Turn dough out onto a floured countertop; roll into a large, 1/2-inch-thick circle. Use a 1 1/2-inch cookie cutter to form biscuits. Gather scraps into a ball, roll and cut again.
4. Place 12 biscuits on a baking sheet. Bake until lightly browned, 15 to 18 minutes. Repeat with remaining biscuits.
