Lasagna roll-ups are a fun and innovative way to enjoy this classic dish. Instead of layering the ingredients, lasagna noodles are cooked, filled with a delicious mixture of sautéed mushrooms, spinach, and ricotta cheese, and then rolled up. The roll-ups are placed in a baking dish, topped with marinara sauce and mozzarella cheese, and baked until bubbly and golden. The individual portions make serving and portion control a breeze, and the combination of mushrooms and spinach adds a hearty and earthy flavor to the dish.
