Polish Meatloaf Stuffed with Mushrooms is a hearty and flavorful dish that combines ground meat with a savory mushroom filling. The meatloaf is made by mixing ground beef or pork with breadcrumbs, eggs, and seasonings. A mixture of sautéed mushrooms, onions, and garlic is then spread onto the meat mixture, and the whole thing is rolled up into a loaf shape. It is baked until golden and cooked through, resulting in a juicy and delicious meatloaf with a surprise mushroom filling. This Polish comfort food is perfect for a family dinner or special occasion.
