Slice each chicken breast horizontally nearly in half to butterfly. Open up, and sprinkle with lemon juice on both sides. Sprinkle with pepper and chipotle powder to taste, then add a slice of Brie, and sprinkle with chives. Fold the chicken breasts back together firmly.
Place 3 slices of prosciutto side by side, pointing away from you, with each overlapping by 1/3. Place a stuffed breast upside down onto the bottom edge of the prosciutto. Roll one complete turn (so the breast is upside down again) fold in the sides, then continue rolling to the end of the prosciutto.
Place chicken packets seam-side down onto oiled baking dish. Bake in preheated oven until the internal temperature of the chicken reaches 160 degrees F (70 degrees C), about 40 minutes. Allow to rest for 5 minutes before serving.
