Ingredients for 40 servings:
1. 2 cups pot barley
2. 2 cups brown rice
3. 2 cups diced carrots
4. 2 cups fresh spinach
5. 2 cups chopped beef heart
6. 1 cup lentils
7. 1 cup diced celery
8. 2 garlic cloves, minced
9. 10 cups water

Directions:
1. In a large stock pot, combine all ingredients.
2. Bring the mix to a boil over medium-high heat, then reduce to a simmer for 1 1/2 hours. Put a lid on the pot and stir every 15 minutes or so.
3. You may need to add more water (I always do).
4. Allow to cool before offering to your dog. Leftovers can be refrigerated or frozen.

Enjoy your meal!
