1 pound extra lean ground beef or ground turkey
2 cups shredded cabbage
1 medium green bell pepper, finely chopped
1 teaspoon salt
1/4 teaspoon garlic powder
1/4 teaspoon celery seed
1 tablespoon dried minced onion
1 egg, beaten

First, make foil "handles." Fold a 30-inch long piece of foil in half lengthwise. Place in bottom of a slow cooker with both ends hanging over top edge of cooker.The foil strip will make it much easier to remove the meatloaf when it's done.

I also put a piece of crumpled foil in the bottom to keep the meatloaf out of the fat.
Combine all ingredients; working with hands until blended. Shape into round loaf. Place meat loaf on rack or crumpled foil in 3 1/2 to 5-quart crockpot. Cover and cook on high for 4 to 6 hours.
