Make sure to make this ahead of time~! I use 1 cube with 1 cup of water to replace beef broth.
3 cups celery, minced
3 cups carrots, minced
2 onions, minced
2 tablespoons salt
1/2 lb ground beef
Combine all ingredients in a saucepan without any liquid.
Cook over very low heat, covered, for 1 hour.
Place contents into a blender or food processor and process until smooth.
Pour into ice cube trays and freeze.
Makes 2 Ice cube trays worth
