Combine all ingredients: cooked turkey, rinsed rice, diced carrots, diced celery, diced onion, frozen peas, cream of mushroom soup, chicken broth, soy sauce, garlic powder, onion powder, salt, and pepper in a crockpot.

Stir well to ensure the rice is fully submerged in the broth.

Cover and cook on low for 3-4 hours. Check rice tenderness after about 3 hours.

Fluff the rice with a fork once cooking is complete and serve hot.
