Preheat oven to 350ºF and line a rimmed baking sheet with parchment paper.
Make the meatballs: Add the ground turkey, salt and spices to a large bowl and mix together until fully combined. Roll meat mixture into 1-½” balls (about 3 tablespoons each) and place on the rimmed baking sheet.
Bake for 10-15 minutes, or until the meatballs are fully cooked through to a temperature of 165ºF degrees.
Meanwhile, make the soup: Heat oil over medium heat in a large dutch oven. Once hot, add carrots, onion, garlic, pepper and a big pinch of salt, and cook until beginning to soften about 10 minutes.
Add in 6 cups of chicken stock, kale, zucchini, beans, tomatoes, salt, pepper and spices and bring the soup up to a boil.
Lower the heat to a simmer for 5-10 minutes, or until the kale is wilted. Add in cooked meatballs and simmer for 5 more minutes. Add in more broth, if desired.
Add in the lemon juice and season to taste with additional salt and pepper.
