This recipe is a delicious and healthy twist on traditional lasagna. Instead of using pasta noodles, this recipe uses spaghetti squash as the base. The squash is roasted until tender and then layered with a mixture of ricotta cheese, ground beef, and tomato sauce. The result is a hearty and satisfying meal that is low in carbs and high in protein. To make this dish, start by roasting the spaghetti squash in the oven until it is tender. While the squash is roasting, cook the ground beef in a pan until it is browned. In a separate bowl, mix together ricotta cheese, parmesan cheese, and egg. Once the squash is done, use a fork to scrape out the flesh and layer it in a baking dish with the ground beef and tomato sauce. Top with the ricotta cheese mixture and bake in the oven until the cheese is melted and bubbly. Serve hot and enjoy!
