Melt butter in a small skillet over medium heat. Add minced garlic; saute 30 seconds or until lightly browned. Remove from heat; stir in garlic powder. Unroll the French bread dough onto a lightly floured surface; brush dough with garlic mixture. Sprinkle the dough with chives and cheese. Cut the dough crosswise into 12 strips. Shape each strip into a knot. Place the knots onto a baking sheet coated with cooking spray. Bake at 350 degrees for 17 minutes or until lightly browned. Serve warm.
