1. Preheat the oven to 350°F. 2. Place 6 oven-proof cups or jars (about size of standard coffee cup or small canning jar used for jellies) upside down on a rimmed baking sheet. 3. Lightly oil both sides of each tortilla with olive oil and drape one over each cup or jar, pressing down the sides gently to form the shape of an upside down bowl. 4. Bake the tortilla bowls for approximately 8 to 10 minutes until they are lightly browned and crisp, checking occasionally to make sure they don't burn and rotating if needed. Allow to cool before removing from cup or jar. Prepare fillings as they are cooling. 5. In a skillet, over medium heat, brown the turkey. Add the taco seasoning and cook according to package directions. 6. To serve, fill each tortilla bowl with the seasoned ground turkey and top with cheese, onions, tomatoes, lettuce, and sour cream as desired. Serve with fresh salsa on the side.
