I have two creative loaves that I like to make. The first one, I call it a Mexican Volcano. I use a mixture of ground beef, and a spicy sausage such as chorizo. I then add an egg, some breadcrumbs, a bit of milk, and season it with mild and hot diced peppers, diced onion, cumin, cilantro, coriander, and garlic. I form it into a mountain, with a crater on top. I do this on a foil lined jelly-roll pan. I stick a meat thermometer in it and roast in a 400' oven until the thermometer reads 160 F. I then remove it from the oven, sop up the grease with paper towels, and then put enchilada sauce into the crater until it spills over the top like hot lava. Then, I place bits of shredded Monterrey Jack cheese into the "lava" rivulets to mimic glowing lava. I put it back into the oven for another ten minutes to melt the cheese, and get the sauce hot. To make it even more spectacular, I spread re-fried beans over the pan, and stand broccoli flowerettes in the beans, to make little trees.
The second loaf is made the same way, but with ground beef and Italian Sausage. Herbs include a fair amount of oregano, basil, thyme, rosemary, and with the diced onion and sweet pepper. In this one, Parmigiano Regiano is used with marinara sauce for the lava.
Be creative with your meatloaf. Try placing the mixture into a piping bag, with not decorating insert, and squeezing out a tube that is side at the bottom, and spirals upward into a cone. Any thing is possible. Enjoy the process as well as the recipe.
