http://allrecipes.com/recipe/turkey-and-yam-spicy-tacos/Detail.aspx 

Ingredients

•   2-3 yams, peeled and diced
• 1 tablespoon olive oil
• 1-2 pounds ground turkey
• 1 cup chopped sweet onion
• 2 cloves garlic, minced
• 4 jalapeno peppers, seeded and minced
• 2 tablespoon chili powder
• 2 teaspoon ground cumin
• 1/2-1 teaspoon Cajun seasoning
• 1 teaspoon salt
• 1-11/2 cup tomatillo salsa
• 1/2 cup chopped parsley or fresh cilantro
• 16 warm flour tortillas

Directions

1. Put the diced yam in 400 degree oven for about 20 minutes and roast.  Before roasting pour on a little olive oil and kosher salt and pepper from a mill.  You could just put it in a microwave-safe bowl; cook in the microwave until cooked through and fork-tender, stirring once, 5 to 7 minutes. 
2. Coat the bottom of a large skillet with olive oil and place over medium heat; cook and stir the turkey until crumbled and evenly brown, 5 to 7 minutes. Stir the onion, garlic, and jalapeno pepper into the turkey and continue cooking until the onions begin to caramelize, 7 to 10 minutes. Season with the chili powder, cumin, Cajun seasoning, and salt. Pour the salsa over everything; fold the sweet potatoes into the mixture. Allow the mixture to cook until the excess moisture evaporates. Garnish with cheese, Creamy Guacamole (recipe follows), lettuce, tomatoes, cilantro, etc.. Serve with the warm tortillas.
