In a medium bowl, add 1 cup Greek yogurt, 1 Tbsp lemon juice, 2 tsp cumin, 1 tsp cinnamon, 2 tsp Chili powder, 2 tsp black pepper, 1 Tbsp ginger, 1/2 tsp salt and then whisk well to combine, set aside.
On a cutting board, remove the silver skin from the pork tenderloin and then cut into 1-inch-thick slices.
Place the cut tenderloins into the mixture and then mix well. Cover the bowl and rest in the fridge for at least 1 hour.
In a large saucepan, heat 1 tablespoon oil, then cook the marinated pork tenderloin until the juices run clear, around 10-15 minutes.
Once the pork tenderloin is cooked, remove it from the saucepan and then place it in a dish and set aside.
