Stuffed tenderloin is one my Mexican families favorite dishes. We try to prepare it for special occasions, like our Sunday reunions or birthday parties. Stuffed tenderloin is a simply prepared dish and will make your dining table look wonderful. You can fill it with nearly anything, but in my house we generally use a mix of garlic, ham and herbs. This time I added raisins to give it a light sweetness. Serve with green salad and mashed potatoes.
