Step 1) Preheat oven to 425℉. Line a roasting pan with aluminum foil.
Step 2) Combine 1 tablespoon oil, 2 tablespoons mustard, garlic powder, salt and pepper in a small bowl. Place pork tenderloins on a baking sheet and coat completely with mustard mixture.
Step 3) Combine all crust ingredients except bread crumbs in a medium bowl. Add bread crumbs and stir to mix completely with a fork. Pour bread crumbs over pork, rolling to coat all sides with crumbs. Press any remaining crumbs onto the tops of the meat.
Step 4) Place tenderloins in roasting pan and bake for 20 minutes. Reduce heat to 350℉ and continue baking for 20 to 30 minutes or until internal temperature is at least 150℉. Cover with aluminum foil if crust is becoming too dark.
Step 5) To serve, transfer pork to a serving plate. Let rest 5 minutes and slice into medallions.
