The BEST Meatloaf I’ve ever had was one I called The Collaborative Meatloaf.   On that night each cook took turns adding an ingredient, the rule was you could only add one ingredient per turn and you must disclose what you added.  We made it the way REALLY Good Meatloaf should be made….by starting with good quality meat, adding fresh veggies, binding ingredients like eggs, milk, bread, herbs & aromatics, and then a few secret ingredients.  The problem with our original Collaborative Meatloaf  recipe is we also took turns making cocktails and I’m afraid the ‘secret’ ingredients will remain a secret.
