Soak the bread crumbs in milk. Preheat the oven to 450 degrees. Lightly grease a loaf pan.
Heat the olive oil. When hot add the onions and saute for about 8 minutes or until golden and beginning to brown. Add the garlic and saute for a few seconds. Remove the skillet from the heat and transfer the contents to a mixing bowl.
Add the soaked bread crumbs, ground chuck and ground pork butt and mix with 1 egg. Add grated cheese, fennel, oregano, and parsley. Season to taste with salt and pepper. (Saute some of the mixture before tasting and adjusting for seasoning.)
Transfer the mix to a loaf pan and bake at high heat for 15 minutes. Lower the heat to 350 degrees and bake for 1 hour or until the internal temperature reaches 165 degrees. Let rest 15 minutes before cutting.
