For an extra layer of flavor, try adding a dash of smoked paprika or a pinch of cayenne pepper to the sauce. If you prefer a sweeter taste, you can substitute honey or maple syrup for the coconut sugar. To make this recipe even healthier, use whole wheat hamburger buns or serve the Sloppy Tom mixture over lettuce wraps. Ground chicken or lean ground beef can be substituted for ground turkey. The curry ketchup is a key ingredient to the dish. If curry ketchup is unavailable, consider using standard ketchup and add curry powder with salt to taste.
