A traditional recipe of my grandma which is the best soup I have drink ever. (Thanks to 每天都好饿的熊 .)
Chop the Tomato into pieces and cook it in the Wok or Pan with some oil till it get juicy.
Then put it into a Bowl.
Slice the Potato into flakes and cook it in the Wok or Pan with some oil to boost the flavor and aroma.
Then put it with the tomato into a Stockpot.
Slowly pour in some water and put in some salt.
Turn on the fire and cover the Stockpot until the water get red by the tomato juice.
Then Tomato Potato Soup is done.
