Take a large pot of water, add a little salt to it and then bring it to boil. Then, add 450g macaroni pasta to this salty water and sauté for about 8 to 10 minutes or until it becomes firm, but not hard.
After the macaroni pasta gets al dente, rinse it in cold water and then drain it.
Now combine 1 bunch of sliced radishes, 1 or 2 spring onions, 6 thin chopped celery sticks, 4 tablespoons mayonnaise, salt, pepper to taste with cooked macaroni noodle in a large bowl.
Mix all these ingredients together and then allow this mixture of pasta to chill. When it is chilled, serve it to the guests.
