How to Make It
Heat oven to 375° F. Line a baking sheet with parchment. Heat 1 tablespoon oil in a large skillet over medium-high heat. Add the turkey, onion, garlic, and cumin and cook, breaking the meat up with a spoon, until browned, 3 to 5 minutes. Stir in the raisins and olives; season with ½ teaspoon salt and ¼ teaspoon pepper.
Top the 4 piecrust halves with the turkey mixture; fold in half and seal the edges. Place on the prepared baking sheet and bake until golden, 20 to 25 minutes.
Meanwhile, in a large bowl, toss the greens, cucumber, and radishes with the vinegar and the remaining 3 tablespoons oil. Serve with the empanadas.
