In a small bowl, add the cut up bread. Pour the milk over and give and stir. Let stand while you get the other ingredients ready.
In a large bowl, add the ground beef. Add salt, pepper, garlic and Worcestershire sauce and the bread mixture.
Start combining the ingredients by stirring with a spoon. Once the ingredients are distributed throughout a bit, start mixing with your hands. Do not handle the meat too much, mix just until combined.
Roll out into 6 balls and place on a parchment lined baking pan. Top the balls with another piece of parchment and mash the burgers down into patties (about 3/4-inch thick). Using your thumb, make an indention in the center of each burger.
Grill burgers as desired on preheated grill. Toast buns, split sides down, on grill the last couple of minutes of grilling.
Serve with desired toppings.
