If your kids are taco fans, they'll love to fill their shells with this mildly spicy turkey meat and pile them high with toppings. The turkey filling can also be used for nachos, quesadillas and burritos.
Heat the oil over medium heat in a large skillet. Add the onion and cook for 1 to 2 minutes. Add the tomato sauce, water, chili powder, cumin and salt.
Bring to a boil, then reduce to a simmer and cook for 2 to 3 minutes. Stir in the turkey and cook until heated through.
Place 1/4 cup of the taco filling in each taco shell. Top with 1 tablespoon of shredded cheddar, lettuce, tomato, avocado and olives. Serves 6.
