In a frying pan over medium heat, add the cooking oil. Add in ground turkey and break up into small pieces with a spatula. Add the chopped sweet potatoes and cook until ground turkey is no longer pink (about 2-3 minutes).
Next, add the minced garlic, chopped onion and all spices. Cook another 10 minutes or until sweet potato is tender when poked with a fork. Stir the mixture occasionally during this process.
Sprinkle the top with mozzarella cheese. Dish on to plates and serve.
