Just a beautifully simple subjective cut of meat. With an open mind there are so many preparation options. The most common is to roast whole with your favorite herbs and spices. Stuff with spinach, mushrooms, cheeses, nearly anything. Imagine a pizza ingredient stuffed tenderloin... now google the recipe, it's there. Slice to a desired thickness and grill or sear. Smoke the tenderloin. Chop into cubes and make Kabobs. Limitless!
