PREPARATION:

1. Cook lasagna noodles according to package directions, omitting salt. Drain and rinse well under cold water. Place in single layer on aluminum foil.
2. Preheat oven to 375°F. Place chicken in food processor or blender; process until finely chopped. Spray large nonstick skillet with cooking spray; heat over medium heat. Add chicken; cook 4 minutes or until chicken is no longer pink. Stir in broccoli; cook about 3 minutes or until broccoli is crisp-tender. Cool.
3. Combine cottage cheese, egg, chives, nutmeg and black pepper in medium bowl. Stir in chicken mixture. Spread a generous 1/3 cup filling over each lasagna noodle. Roll up noodle, starting at short end. Place filled roll, seam side down, in 11X7-inch baking dish; set aside.
4. Melt margarine in small saucepan. Stir in flour; cook 1 minute. Whisk in chicken broth, milk and mustard. Cook, stirring constantly, until thickened. Pour sauce over filled rolls; sprinkle with tomato. Cover dish with foil. Bake 30 to 35 minutes or until filling is set. Garnish as desired.
