For the meatballs: Soak the bread cubes in the milk; squeeze dry and place in a large bowl. Add the ground beef, ground pork, ground lamb, onions, Parmesan, bologna, garlic, jalapeno, 1 1/2 teaspoons salt and 2 teaspoons pepper; mix well with a wooden spoon. Form into 2-inch balls.
Heat the oil in a large skillet over medium-high heat. Shallow-fry the meatballs until browned on all sides, 1 1/2 minutes per side. (The meatballs will be raw in the center; they'll finish cooking in the sauce.)
For the BBQ sauce: Heat the oil in a medium saucepan over medium heat. Add the onions; cook for 2 minutes. Reduce the heat to low and add the ketchup, brown sugar, vinegar, chili powder, garlic powder and onion powder; simmer for 5 minutes.
Add the meatballs to the sauce and simmer, covered, for 10 minutes. Serve hot.
