Heat oven to 400°F. In 2-quart saucepan, heat 1 cup water to boiling. Add carrots and broccoli; cook about 4 minutes or until carrots and broccoli are crisp-tender. Drain.
Meanwhile, in 3-quart saucepan, melt butter over medium heat. Add onion; cook about 2 minutes, stirring occasionally, until tender. Beat in flour with wire whisk. Gradually beat in broth and sage. Reduce heat to medium-low; cook about 5 minutes, stirring occasionally, until sauce thickens.
Stir carrots, broccoli and turkey into sauce. Spoon turkey mixture into ungreased 2-quart casserole.
Place bacon on microwavable plate; cover with microwavable paper towel. Microwave on High 4 to 6 minutes or until crisp. Crumble bacon; place in medium bowl. Add remaining biscuit ingredients; stir just until blended. Spoon biscuit batter around edge of turkey mixture.
Bake uncovered 25 to 30 minutes or until biscuit crust is golden brown.
