Once the onion is golden, stir in the tomato paste, ¾ teaspoon of cumin, and ⅛ teaspoon of red pepper flakes. Sauté until the paste darkens, about 1 minute. Add the turkey, garlic, ginger, and 1 teaspoon of salt, and cook while breaking up the meat, until the turkey is browned in spots, 4 to 7 minutes.
