Start by cooking the bacon, diced onion and minced garlic together in a large pan set over medium-high heat until the onion is soft and the bacon is starting to crisp.
Remove from the pan and add to a large mixing bowl. Allow to cool.
Cut the crusts off the white bread then place in a small bowl. Pour the milk over the bread and allow to soak for 5 minutes.
Once the bacon is cool, add to a large mixing bowl along with the soaked bread, beaten egg, beef and all the seasoning.
Mix well then form meatballs with wet hands. This prevent the meatball mixture from sticking to your hands. You can also use an ice cream scoop to portion out the meatballs and form them lightly.
Cook the meatballs in a large, deep skillet or pan over medium-high heat in a splash of olive oil until golden brown on all sides.
Remove from the pan and set aside.
Make the tomato sauce in the same pan by sautéing another chopped onion, garlic and fresh basil then pour in two cans of crushed tomatoes and a half can of water.
Season with salt and pepper then bring to a simmer and add the meatballs.
Cook for 15 minutes until the meatballs are tender and cooked through then serve over cream polenta topped with Parmesan cheese.
