Directions:
Preheat oven to 375°F (190°C).
Arrange potato slices in a greased baking dish. Drizzle with olive oil, sprinkle with salt, black pepper, and 1/2 tsp sweet paprika.
Bake for 20 minutes until potatoes start to soften.
Meanwhile, in a skillet over medium heat, sauté onions and ground beef with salt, black pepper, 1/2 tsp sweet paprika, and oregano until beef is browned.
Stir in crushed tomatoes and simmer for 10 minutes.
Spoon the beef mixture over the pre-baked potatoes. If using, sprinkle mozzarella cheese on top.
Bake for an additional 15-20 minutes until the cheese is bubbly and golden.
Serve hot from the oven.
