| I usually make it with ground beef, egg, bread crumbs, seasonings (salt, pepper, garlic), diced onions, diced bell peppers, and 1/4 can tomato sauce. Then, I lay the mixture out in a rectangle. I sprinkle some grated cheese. This can be anything you want. You could also use a mixture of cheese and cooked rice. Roll up the mixture as to keep the cheese mixture inside. Pour the leftover tomato sauce on the top. Bake as you would any other meatloaf. The family thinks you are SO cool when they cut into the meatloaf and there is cheese inside. You could also put parsley in the cheese mixture for added color.
One other recipe that I make are meatloaf pinwheels. I make a rice mixture with rice and parlsey and maybe a little cheese to help hold it together. Then, I spread it on a rectangle flattened meat mixture. Then, roll it, jellyroll fashion. Wrap in plastic and place in fridge for a few hours. Then, slice and bake as you would a meatloaf, except use a cookie sheet and don't cook as long. This is my DHs fave, but since I started college, I don't cook it as often as it is a bit of work. |
