I have been making meatloaf for years and years, always the same way with minor variations, but always with saltine cracker crumbs as the binder. Recently, I tried oats. Well! Quick-cooking oats (not instant) make a surprisingly good substitute for either cracker crumbs or bread crumbs in a meatloaf. I have also made this meatloaf without any garlic, and it's just as good. Make sure the onions are chopped up fairly small; the texture of the meatloaf is best that way. Also, don't use extra-lean ground beef as you risk having a dry meatloaf rather than a moist one. Leftovers make a wonderful cold sandwich!
