Pour water into a 20-quart pot and bring to a boil over high heat.

Once boiling, add the chana dal, brown lentils, black-eyed peas, green split peas, and barley to the pot. Reduce the heat to medium and stir occasionally.

Cut the chicken breast into bite-sized pieces and add it to the pot.

Add the ground turkey to the pot and stir to combine.

Stir in the pumpkin puree until well incorporated.

Gradually add in as much of the frozen vegetables as will fit in your pot. (If your pot cannot accommodate all the vegetables at once, thaw the remaining vegetables and add them in before storing the finished food.)

Reduce the heat to medium-low and continue to stir until most of the water has been absorbed and the ingredients have been cooked through.

Remove the pot from heat and let the food stand until cooled to room temperature.

Once cooled, portion the food into storage containers or resealable bags. The food can be refrigerated for up to 5 days or frozen for longer storage.

Note: This recipe makes a large batch of food suitable for meal-prepping or feeding multiple dogs. Adjust the quantities as needed based on your dog's size, weight, and dietary needs. Always consult with your veterinarian before making significant changes to your dog's diet.
