Nicko shows us how to make a mouth-watering homemade lasagna. Lasagna is a very easy dish to make. This is a healthier version. Ingredients include celery, zucchini, onion, carrots, beef, lasagna sheets, oregano, cheese, beef stock, tomato paste, crushed tomatoes and skimmed milk. Saute the onions and some garlic until the onions are golden brown. Add chopped vegetables and stir until they are soft. Then add the beef and cook until the meat is brown. Season with oregano, salt and pepper. The tomato paste, crushed tomatoes and beef stock are added to the pot and left to simmer. Next make the cheese sauce with skimmed milk. Then build up your lasagna in layers. Finally, put it in the oven to bake and after 45 to 50 minutes, out comes the tasty lasagna.
