Pierce each brat with a fork, and place in a large saucepan. Top with onion and coleslaw mix; sprinkle with caraway seeds. Pour apple cider over cabbage mixture; bring to a boil. Cover, reduce heat to medium, and cook 20 minutes or until cabbage is tender. Remove brats, and set aside.
Drain cabbage mixture well, reserving 2 tablespoons cooking liquid. Discard remaining cooking liquid. Combine cabbage mixture, reserved cooking liquid, and Thousand Island dressing in a large bowl; toss to coat. Cover and chill.
Combine mustard and honey in a small bowl; set aside. Place a large nonstick skillet coated with cooking spray over medium-high heat until hot. Add brats to pan; cook about 6 minutes or until golden brown on all sides, turning often and basting with honey mixture. For grown up servings, place 1 brat in a bun with 1/3 cup slaw. For plain servings, server brats in bun without the slaw.
