Preheat your oven to 400°F and line a baking sheet with aluminum foil or parchment, then set aside.

In a large mixing bowl, mix together the ground beef and pork, breadcrumbs, eggs, olive oil, parsley, garlic and onion powders, salt, and pepper until thoroughly combined.

Roll the mixture into 2-inch wide balls and place them onto your prepared baking sheet, leaving about ½ inch of space in between each meatball.

Bake the meatballs for 18-20 minutes, or until they are golden brown on top and fully cooked in the middle.

Meanwhile, cut the sliced provolone into 1-inch circles. A small cookie cutter works best for this.

Remove the meatballs from the oven, and place one circle of provolone atop each meatball to create the whites of the eyeballs.

Place one slice of black olive atop each provolone circle to create the irises/pupils of the eyes.

Return the meatballs to the oven for 2-3 minutes or until the provolone has just slightly melted, then remove them from the oven again and set aside.

While the meatballs are cooking, boil the spaghetti in a pot on the stove according to the package instructions.

Heat the marinara sauce in the pot and stir in the spaghetti once warmed through.

Use tongs to scoop out a serving of spaghetti onto each plate and nestle the meatballs over the top.

Top with additional parsley, if desired, and serve.
