Pour water to cover the macaroni, and after about 10 minutes as the water starts to boil, cut the macaroni in half with a spoon to see if it is cooked, rinse it in cold water to cool it down completely and drain it. (Stir while boiling, and pour more water if it's not enough.)

I prepared 1/4 carrots, 1/3 cucumbers, 1/2 purple onions, and half Korean melon The melon and cucumber were used with the skin except for the middle seed. Cut them all into small rectangular shapes in the same size.

Use a kitchen towel to remove moisture from vegetables and macaroni

Place macaroni and vegetables in a large bowl, mix 2 cups mayonnaise, 2 tablespoons mustard sauce, 2 tablespoons brown sugar, 2 tablespoons salt.

The finished macaroni salad tastes better if you put it in an airtight container and put it in the refrigerator
