This delicious recipe swaps in thin slices of zucchini for the noodles. It is low in carbs, so you can easily incorporate it into your diet. The original recipe can be found at Skinny Taste. It is made with lean beef, tomatoes, onions, garlic, olive oil, zucchini, ricotta, mozzarella cheese, and eggs. I’ve used marinara sauce instead of tomatoes and everything came out great. Brown the meat in a medium pan, then drain it in colander and set it aside. Sauté onions and garlic in the pan for two minutes. Put back the meat in the pan, add tomatoes and spices, and simmer for at least half an hour. Cut zucchini into thick slices, add salt, and set aside for a few minutes. After removing excess moisture, grill them on each side. Mix ricotta cheese, parmesan and eggs in a bowl. To assemble, scatter the vegetables along with the cheese mixture between the layers of zucchini. Add sauce and mozzarella on top. Bake for 45 minutes.
