Lentil soup

Ingredients:
half of medium onion
1 cup lentils
1 carrot (mid-size)
1 potato (mid-size)
3 tbsp vegetable oil
5 cups boiled water
salt, mint, blackpepper

Put oil and small chopped onion into a pot and roast it. Next, add chopped(Note:it must be chopped with grater) carrot and potato into the pot and roast them all(onion,carrot, and potato) together. After that put washed lentils into the pot and mix them about 30 seconds,and pour boiled water on top of the mixture. Then, boil it until the lentils are become firm(you may bite lentils to check if it is firm or not). Now your soup is ready, but do not forget to put a salt,1 tbsp a blackpepper, and 1 tsp of a mint into the pot.  Finally, I would like to recommend you to mix with mixer about 2 minutes in order to make your soup more delicious.  Bon Appetit!
