Preheat the oven to 400 degrees F. Line a baking sheet with foil;
then lightly coat the foil with nonstick spray.
In the bowl of a food processor, pulse the bread until they
resemble crumbs.
Heat a small skillet over medium heat. Add the bread crumbs and
toast until golden brown, about 4-5 minutes.
In a small bowl, combine the toasted bread crumbs and milk; let
stand until all of the milk is absorbed.
In a large bowl, add the breadcrumb mixture, ground beef, grated
onion, sour cream, egg, salt and pepper.
Using a wooden spoon or clean hands, stir until well combined.
Roll the mixture into 1 1/4-to-1 1/2-inch meatballs and place on
onto prepared baking sheet.
Drizzle a small amount of mayonnaise on each meatball.
In a small bowl, combine the mozzarella and Parmesan. Sprinkle
each meatball with 1 tablespoon cheese mixture.
