# Dice the
onion finely and fry it in vegetable oil, until it turns to transparent.
# Add peeled and cut into cubes
tomato on it. Cover the lid of the pot, and cook it until the
tomato seems as
tomato paste.
# Strain the cooked mixture of
tomato and
onion by a strainer, which has big holes. Then put it into the pot again.
# Add 1 tbsp
flour into the mixture, and roast it for about 4-5 minutes, until the smell of the
flour goes away.
# Meanwhile, boil the orzo in a separate pot with enough water, without losing its original shape.
# When the smell of
flour goes away, add 7 cups of water or broth into the
tomato mixture.
# When the soup reaches to the boiling temperature, add the boiled orzo in it and add salt also. Cook it over low heat for 10 more minutes, then remove it from the stove.
# Fill the hot soup into the bowls, sprinkle grated kasar
cheese all over.
