Begin by placing the white bread in a bowl. Cover with the milk - ensuring that all of the bread is moistened by the milk. Let it sit for 5-10 minutes while you get the rest of the ingredients together.

Place the ground beef in a large mixing bowl. Add the soaked bread (crumble it between your fingers into very small pieces to ensure it gets evenly incorporated), eggs, garlic, parsley, oregano, parmesan cheese, currants, pine nuts, breadcrumbs, salt, allspice, pepper, and red pepper flakes. Work the meat together with your hands, making sure all of the ingredients are evenly incorporated. Be careful to not overwork your meat - or else you can end up with tough, dry meatballs! Form the meat into golf ball-sized meatballs - you should get 20-22 meatballs total.

Heat a large nonstick skillet over medium to medium-high heat. Once hot, add the meatballs in batches, cooking for about 2 minutes per side, 4-5 minutes total, rolling them around on all sides for even cooking, until golden brown on the outside. Transfer meatballs to a rimmed baking sheet or plate.

Meanwhile, make the sauce. In a large pot or dutch oven, heat the olive oil over medium heat. Once hot, add the garlic and sauté for 30 seconds - 1 minute or until fragrant. Add the crushed tomatoes, tomato sauce, and salt. Stir to combine. Cover and bring sauce to a simmer. Once simmering, add the meatballs, gently stirring them into the sauce. Cover and simmer over medium-low heat for at least 30 minutes. An hour or longer is even better!

Season to taste the sauce with additional salt if needed. Serve meatballs with freshly grated parm, a baguette, pasta, or as a meatball sandwich!
