Bring a large pot of lightly salted water to a boil. Cook spaghetti for about 12 minutes, until tender but firm. Drain and set aside. Preheat the oven to 400°F (200°C).
Mix Parmesan, panko, egg, garlic, parsley, basil, and oregano in a large bowl. Fold in the ground beef and form 16 equal-sized meatballs.
Heat olive oil in a large skillet over medium-high heat. Brown meatballs for 3 minutes per side. Transfer them to a baking sheet and bake for 8 minutes, or until the center reaches 160°F (71°C).
Punch pupils from the olive halves and holes in the string-cheese slices with a plastic straw. Insert the olive pieces into the cheese. Cool the meatballs briefly, add a small dot of sauce, place one eye on each meatball, and serve over spaghetti with warm sauce.
