In a small bowl, stir together the ancho powder, cumin and Mexican oregano.

In a nonstick frying pan, add the ground turkey and onion. Cook over medium heat until the turkey is browned and onion is translucent. Drain well. Add the spices to the turkey mixture. Stir to mix evenly.

To serve, place a 1/4 cup of the turkey mixture in each tortilla. Top each with 1 tablespoon cheese, 1/4 of the diced tomatoes, 1/2 cup shredded lettuce and 2 tablespoons salsa. Fold in both sides of each tortilla up over the filling, and then roll to close. Serve immediately.
