In a bowl, combine all ingredients except bread and oil. Mix thoroughly.
Wet half of bread with water, then squeeze out excess water. Tear into small pieces and add to meat mixture. Mix with your hands. It should be sticky but hold together. If too wet (not holding together), wet remaining bread, squeeze out excess water, and add in pieces as necessary to make mixture sticky and hold together.
In a sauté pan or skillet over medium heat, warm 1 inch of olive oil until hot. Using 1⁄4 cup of meat mixture at a time, form meatballs by hand or with an ice cream scoop. Add to oil (meatball should sizzle). Turn to brown on all sides. Drain meatballs on paper towels and serve with your favorite sauce.
