1. Add one gram of yeast to the flour, a pinch of salt, 5 grams of butter and a little milk. Let it rise in a warm place for two hours so that it expands

2. Cut all the vegetables into strips

3. Add a little oil to the pan and cook the sausage first (the sausage is home-filled, the meat is not so crumbly), and when the sausage is half-cooked, put in the mushrooms, a part of onion, and a part of the peppers, and stir-fry out of the pan. (Add salt and black pepper to taste when sautéing)

4. Roll out the risen dough into a sheet and place it in a pizza pan, cut the mozzarella into strips and place them evenly around the edge of the pie, wrapping it tightly with the extra crust. (In order to make the edge of the cheese pie)

5. In the pastry with a toothpick to make holes, spread a layer of pizza sauce or tomato sauce, put a layer of mozzarella, and then evenly pour the fried vegetables on the top, baked in the oven at 200 degrees for 8 to 10 minutes. Remember to spread the edges of the pie with egg wash (the edges will be crispy and golden brown)

6. Remove from the oven and spread the remaining onions and peppers and tomato slices on top, and finally a layer of mozzarella cheese, and bake at 200 degrees for 10 minutes

7. Remove from the oven
