I use a basic meatloaf recipe but use half ground beef and half ground pork. Found a recipe that calls for spreading out the meat mixture and adding a layer of sauteed onions, mushrooms, gravy, peppers and shredded cheese, then roll it all up and bake. 15 minutes before its done you pull it out and add the remaining sauteed onion mixture to the top and more shredded cheese and finish baking. Came out great for me the 1st time and it was for guests too. I do add worstershire to my meat mixture as I fine that always give a little more spunk to the taste.
