Preheat the oven to 450 degrees F.
Place the bread slices in a large mixing bowl and dampen with heavy cream. Once bread is soaked through, add the rest of the ingredients, except the meat, and mix well. Mix in the meat. Roll the mixture into 1-inch meatballs and bake, uncovered, on a lightly greased baking pan for 45 minutes.
Serve the meatballs hot, with gravy if desired.
