What's better than gooey warm rat guts on Halloween? A quick and easy meatloaf that the youngsters can eat on the run! I've included a basic recipe, but feel free to use your family's favorite. Use pearl onions in place of the olives for a different look. The layer of crushed French-fried onions will resemble burnt fur! When you slice it, the 'guts' should ooze out and make quite an impression.
