"Create a hearty dinner recipe for 4 people using 5 potatoes, 600 g minced meat, 3 eggs, sour cream, and rice, plus pantry staples as needed. The user wants something practical with leftovers for the next day. Suggest a comforting baked or skillet-style dish that uses metric units, includes flexible 'other stuff' pantry ingredients, and is suitable for dinner with leftovers."
