1. Preheat oven to 350°. Combine first 8 ingredients in a medium bowl. Add ground turkey and sausage; combine mixture just until blended, using hands. Place mixture on a lightly greased rack in an aluminum foil-lined broiler pan; shape mixture into a 10- x 5-inch loaf. Top with stewed tomatoes, and sprinkle with brown sugar.
2. Bake at 350° for 1 hour and 35 minutes or until a meat thermometer inserted into thickest portion registers 165°. Remove from oven; let stand 20 minutes.
