This recipe is a version that Alton Brown did on Good Eats. I’ve added a few extra ingredients, like mushrooms, which I believe helps make a very moist meatloaf. Do I feel bad stealing Alton’s recipe? No, because he stole it from someone, who stole it from someone, and so on and so on. I’ve tried many recipes and this is my favorite for flavor, texture and it's just plain easy to make.  I believe this is the first demo I make you dust off your food processor for. I know they are a pain to drag out and clean, but they are crucial to this recipe! The real secret to this method is the veggie puree we add to the meat and bread crumbs. Not only do these aromatic vegetables add tons of flavor, more importantly they add moisture to the mix. Most “bad” meatloaves are nothing more than giant baked hamburgers.
