here's an easy and practical recipe
tablespoon olive oil
For assembling the lasagna
Heat a pan/wok, add the olive oil, add the ground beef, season and sir the beef till browned, add the carrots,sausage and the seasoning(basil,salt,oregano or just mixed herbs,some contain sage and dried rosemary) stir in the tomato paste,the water, stir and allow to simmer on low heat for another 25minutes.
To prepare the lasagna, bring some slightly salted water to a boil, add the lasanga and cook for about 10minutes, stirring occasionally. dont allow it to be too soft(al dente). drain teh pasta(lasagna).
In a bowl, mix the cheese and egg. At this point, you need to preheat your oven.mostimes I use just one cheese as opposed to the traditional lasagna with about 2 or 3 cheeses. I use a light mozarella cheese.
Laddle like 3/4 of the meat sauce in the bottom of the baking dish. arrange a layer of lasagna side by side on top of the sauce, spread the cheese mixture over the lasagna and sprinkle some parmesan cheese over it. repeat the steps till you get to the top of the baking dish, then sprinkle the rest of the cheese. wrap the top of the baking dish with a foil and place in the oven, bake for 30minutes, uncover the foil and bake for another 10-15minutes till the cheese is bubbly on top and crusty around the edges. Allow to rest for 10minutes before serving.
