01 - In a large bowl, combine ground turkey, breadcrumbs, egg, minced garlic, Italian seasoning, salt, and pepper. Mix thoroughly until just combined.
02 - Form the mixture into small, evenly sized meatballs. Optionally, heat a nonstick skillet over medium heat and brown meatballs lightly on all sides, turning gently.
03 - Transfer the meatballs to a freezer-safe container. Add chicken broth, sliced carrots, sliced celery, and chopped kale around the meatballs.
04 - Freeze container until ready to use. To prepare, thaw fully in the refrigerator, then transfer contents to a large saucepan. Simmer over medium heat until meatballs are fully cooked and vegetables are tender, about 30 minutes.
