In a large bowl, whisk together the olive oil, vinegar, honey, dijon mustard, garlic, herbs, and seasonings until evenly combined.
Place the turkey in the bowl (or in a gallon-sized Ziplock bag) with the marinade and toss to coat. Cover and refrigerate for 1 to 8 hours to allow the flavors to infuse with the turkey tenderloins.
Preheat the oven to 400 degrees F (roast or bake setting). Spray roasting pan or shallow casserole dish with cooking oil.
Remove the tenderloins from the marinade and discard the marinade. Add turkey breast tenderloins to the roasting pan or dish. If desired, add a hearty vegetable, like potatoes to the roasting pan with the turkey tenderloin.
Roast in the oven for 30-35 minutes. Turkey tenders are done when a thermometer inserted into the thickest part of the tenderloin, registers 165 degrees F. Remove the turkey from the oven and let rest for 10 minutes, before slicing and serving.
Notes
Roasted turkey tenderloins will last up to 4 days stored in a sealed container in the refrigerator. They also are great to freeze! Once cooled transfer them to a freezer-safe zipper bag, and keep them stored for up to 3 months.
