Preheat oven to 350 degrees. Line large cookie sheet with foil, parchment paper or silicone baking mat. Set aside.
In a large bowl, stir all ingredients together excluding the tortillas and butter.
Wrap corn tortillas in damp paper towels and microwave 1-2 minutes or until hot and pliable. Brush melted butter onto one of the sides of the tortilla. Place 1 heaping tablespoon of turkey filling down the center of the tortilla. Fold over and wrap tightly. Brush the outside with more butter and place onto prepared baking sheet. Repeat with remaining tortillas.
Bake 20-25 minutes or until lightly golden and crispy. Serve warm with sour cream, salsa and guacamole.
