I like to make my bolognese mixture using beef mince, pork sausage meat and bacon lardons, it adds a lovely flavour. I also add carrots, celery etc a glass of red wine, chopped tomatoes and herbs and some beef stock cube. Simmer it all for a good 3 hours.
White sauce I add milk to a pan and boil, then I add conrnflour mixed with water to thicken, nutmeg and then grated cheffar cheese.
I then add some cheese sauce to the bottom of a dish, lasagna sheet, bolognese, parma ham, white sauce, cheedar etc Top it off with a layer of cheese sauce topped with cheedar and mozzarella.
