                                Tips: 
                                1. Use sweet potato shreds to make a cake instead of a full-faced foundation, put it in the 170 degree oven and bake it for 10 minutes, let it cook and shape; 2. Match the vegetables at will, try to choose less water, easy to cook and rich in color For the diced vegetables, be careful to blanch and cook the hard-boiled ones in advance; 3. Use mozzarella cheese to make it easy to pull out very long strands.
