Cut all the ingredients into small diced; turn the pork into the end (not too bad), then transfer the salt to a small amount of wine, powder, white pepper, and marinate for 10 minutes. After the pot is hot, put the butter pieces and dissolve, then pour in the minced meat and stir fry. When it turns white, it will be fired and spared.
After adding the butter and adding a little butter to the heat, add the onion and stir-fry until the scent is added. Add the tomatoes and mushrooms and continue to stir fry for a while. After the tomatoes are soft, add more tomato sauce. Salt, chicken, and more black pepper powder continue to be cooked (when seasoning, you can put more food than usual, so that the taste is heavier)
Look at the thickness of the tomato sauce, add a little milk and boil the bolognese sauce before cooking.
Take the rice flat on the deep bottom of the oven, spread a thick layer of sauce evenly, and spread the mozzarella cheese evenly on the sauce. The oven is 220 degrees, the middle layer, the fire, the grilling 10 minutes or so (observe the golden surface of the cheese)
