This recipe has evolved over decades of cooking and really is wonderful. Every component adds something - the grated zucchini, carrot and potato add nutrition, flavour and moistness, and the diced bell pepper just finishes it all off. The vegetables 'melt' into the meat mixture as it cooks, and if you didn't tell someone they were there, no one would be the wiser. I'm asked for the recipe all the time, so here it is. It makes two loaves, as it is our tradition to have leftovers sliced and fried for sandwiches the next day. I've also made this recipe into patties and fried them in a skillet like burgers instead of baking, the whole family loves it.
1Preheat oven to 350 degrees F. Crumble the ground beef and ground pork into a large mixing bowl. Add all ingredients and mix well with your hands. (Disposable kitchen gloves come in handy and help keep your manicure nice for this step but aren't a necessity.)
2Shape into two large loaves. Bake side by side in a 13x9 inch pan, leaving at least a couple inches between the loaves. (I always use a glass pan but metal works as well) for 1-1/2 to 2 hrs.
3Let stand for ten minutes after removing from oven.
4This recipe makes two good sized loaves. It is our tradition that the day after a meatloaf dinner, the leftovers are sliced and fried in a cast iron skillet for sandwiches (on white bread with ketchup), and in order to have leftovers I had to increase the size of the recipe to what you see here.
