In a large mixing bowl, combine your choice of ground meat, breadcrumbs, egg, grated onion, minced garlic, paprika, salt, and pepper. Mix until just combined and form small meatballs.

Heat a tablespoon of olive oil in a large skillet over medium heat and brown the meatballs until golden, approximately 5-7 minutes.

Wash and slice the potatoes about 1/4 inch thick. Toss them with olive oil, salt, and pepper.

Preheat oven to 375°F (190°C). Grease a baking dish, layer potatoes, place meatballs, and sprinkle shredded cheese over everything.

Cover with foil and bake for 25 minutes. Remove foil, add remaining cheese, and bake uncovered for another 10-15 minutes.

Let cool for about 5 minutes, garnish with parsley, and serve warm.
