In a nonstick skillet, brown beef and beef liver over medium-high heat, stirring frequently. Add carrots, green beans, peas and apples while beef is slightly pink. Continue until beef is fully cooked and vegetables are soft. Do not drain. Let the mixture cool until it is warm to the touch.
Choose a pot that will hold all the potatoes, add water and bring to a rapid boil. In the meantime, dice the russet and sweet potatoes (do not peel) to an appropriate bite size for your dog. Add potatoes to the water and lower heat to a simmer. Cook for 10-15 minutes or until fully cooked (soft to the touch). Add ice to stop the cooking process. Drain. Let the potatoes cool to the touch.
In a large mixing bowl, after the food has cooled completely, combine all ingredients, including the sunflower and Omega oils. Slowly sprinkle in DIY Nutrient Blend until fully incorporated.
