Whisk olive oil, apple cider vinegar, dijon mustard, salt, onion powder, herbs and nutmeg together and pour over the turkey tenderloins in a bowl. Toss until fully coated, cover the bowl and place in the fridge to marinate for at least 4 hours.
Remove the tenderloins from the fridge. Preheat the oven to 425F and line a baking sheet with parchment paper.
Place marinated tenderloins on the baking sheet and bake for 18-20 minutes. Check for an internal temperature of 165 and remove from the oven.
Let cool for at least 5 minutes before slicing.
Notes
You can use chicken tenderloin, breast or thighs for this recipe in place of turkey. This change will alter the cook time so please check for an internal temperature of 165F
You can use white vinegar or red wine vinegar in place of the apple cider vinegar
